+In This Release
+===============
+
+This file describes the Linux* Base Driver for the Intel(R) PRO/1000 Family
+of Adapters.  This driver includes support for Itanium(R)2-based systems.
+
+For questions related to hardware requirements, refer to the documentation
+supplied with your Intel PRO/1000 adapter. All hardware requirements listed
+apply to use with Linux.
+
+The following features are now available in supported kernels:
+ - Native VLANs
+ - Channel Bonding (teaming)
+ - SNMP
+
+Channel Bonding documentation can be found in the Linux kernel source:
+/Documentation/networking/bonding.txt
+
+The driver information previously displayed in the /proc filesystem is not
+supported in this release.  Alternatively, you can use ethtool (version 1.6
+or later), lspci, and ifconfig to obtain the same information.
+
+Instructions on updating ethtool can be found in the section "Additional
+Configurations" later in this document.
+
+NOTE: The Intel(R) 82562v 10/100 Network Connection only provides 10/100
+support.

 Command Line Parameters
 =======================
 
+If the driver is built as a module, the  following optional parameters
+are used by entering them on the command line with the modprobe command
+using this syntax:
+
+     modprobe e1000 [<option>=<VAL1>,<VAL2>,...]
+
+For example, with two PRO/1000 PCI adapters, entering:
+
+     modprobe e1000 TxDescriptors=80,128
+
+loads the e1000 driver with 80 TX descriptors for the first adapter and
+128 TX descriptors for the second adapter.

 Additional Configurations
 =========================
 
+  Configuring the Driver on Different Distributions
+  -------------------------------------------------
+  Configuring a network driver to load properly when the system is started
+  is distribution dependent.  Typically, the configuration process involves
+  adding an alias line to /etc/modules.conf or /etc/modprobe.conf as well
+  as editing other system startup scripts and/or configuration files.  Many
+  popular Linux distributions ship with tools to make these changes for you.
+  To learn the proper way to configure a network device for your system,
+  refer to your distribution documentation.  If during this process you are
+  asked for the driver or module name, the name for the Linux Base Driver
+  for the Intel(R) PRO/1000 Family of Adapters is e1000.
+
+  As an example, if you install the e1000 driver for two PRO/1000 adapters
+  (eth0 and eth1) and set the speed and duplex to 10full and 100half, add
+  the following to modules.conf or or modprobe.conf:

+Known Issues
+============
+
+Dropped Receive Packets on Half-duplex 10/100 Networks
+------------------------------------------------------
+If you have an Intel PCI Express adapter running at 10mbps or 100mbps, half-
+duplex, you may observe occasional dropped receive packets.  There are no
+workarounds for this problem in this network configuration.  The network must
+be updated to operate in full-duplex, and/or 1000mbps only.
+
+Jumbo Frames System Requirement
+-------------------------------
+Memory allocation failures have been observed on Linux systems with 64 MB
+of RAM or less that are running Jumbo Frames.  If you are using Jumbo
+Frames, your system may require more than the advertised minimum
+requirement of 64 MB of system memory.
+
+Performance Degradation with Jumbo Frames
+-----------------------------------------
+Degradation in throughput performance may be observed in some Jumbo frames
+environments.  If this is observed, increasing the application's socket
+buffer size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values
+may help.  See the specific application manual and
+/usr/src/linux*/Documentation/
+networking/ip-sysctl.txt for more details.
+
+Jumbo Frames on Foundry BigIron 8000 switch
+-------------------------------------------
+There is a known issue using Jumbo frames when connected to a Foundry
+BigIron 8000 switch.  This is a 3rd party limitation.  If you experience
+loss of packets, lower the MTU size.
+
+Allocating Rx Buffers when Using Jumbo Frames 
+---------------------------------------------
+Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if 
+the available memory is heavily fragmented. This issue may be seen with PCI-X 
+adapters or with packet split disabled. This can be reduced or eliminated 
+by changing the amount of available memory for receive buffer allocation, by
+increasing /proc/sys/vm/min_free_kbytes. 
+
+Multiple Interfaces on Same Ethernet Broadcast Network
+------------------------------------------------------
+Due to the default ARP behavior on Linux, it is not possible to have
+one system on two IP networks in the same Ethernet broadcast domain
+(non-partitioned switch) behave as expected.  All Ethernet interfaces
+will respond to IP traffic for any IP address assigned to the system.
+This results in unbalanced receive traffic.
+
+If you have multiple interfaces in a server, either turn on ARP
+filtering by entering:
+
+    echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+(this only works if your kernel's version is higher than 2.4.5),
+
+NOTE: This setting is not saved across reboots.  The configuration
+change can be made permanent by adding the line:
+    net.ipv4.conf.all.arp_filter = 1
+to the file /etc/sysctl.conf
+
+      or,
+
+install the interfaces in separate broadcast domains (either in
+different switches or in a switch partitioned to VLANs).
+
+82541/82547 can't link or are slow to link with some link partners
+-----------------------------------------------------------------
+There is a known compatibility issue with 82541/82547 and some
+low-end switches where the link will not be established, or will
+be slow to establish.  In particular, these switches are known to
+be incompatible with 82541/82547:
+
+    Planex FXG-08TE
+    I-O Data ETG-SH8
+
+To workaround this issue, the driver can be compiled with an override
+of the PHY's master/slave setting.  Forcing master or forcing slave
+mode will improve time-to-link.
+
+    # make CFLAGS_EXTRA=-DE1000_MASTER_SLAVE=<n>
+
+Where <n> is:
+
+    0 = Hardware default
+    1 = Master mode
+    2 = Slave mode
+    3 = Auto master/slave
+
+Disable rx flow control with ethtool
+------------------------------------
+In order to disable receive flow control using ethtool, you must turn
+off auto-negotiation on the same command line.
+
+For example:
+
+   ethtool -A eth? autoneg off rx off
+
+Unplugging network cable while ethtool -p is running
+----------------------------------------------------

-Identifying Your Adapter
-========================
-
-The e1000e driver supports all PCI Express Intel(R) Gigabit Network
-Connections, except those that are 82575, 82576 and 82580-based*.
-
-* NOTE: The Intel(R) PRO/1000 P Dual Port Server Adapter is supported by
-  the e1000 driver, not the e1000e driver due to the 82546 part being used
-  behind a PCI Express bridge.
-
-For more information on how to identify your adapter, go to the Adapter &
-Driver ID Guide at:
-
-    http://support.intel.com/support/go/network/adapter/idguide.htm
-
-For the latest Intel network drivers for Linux, refer to the following
-website.  In the search field, enter your adapter name or type, or use the
-networking link on the left to search for your adapter:

-
-Command Line Parameters
-=======================
-
-The default value for each parameter is generally the recommended setting,
-unless otherwise noted.
-
-NOTES:  For more information about the InterruptThrottleRate,
-        RxIntDelay, TxIntDelay, RxAbsIntDelay, and TxAbsIntDelay
-        parameters, see the application note at:
-        http://www.intel.com/design/network/applnots/ap450.htm
-
-InterruptThrottleRate
----------------------
-Valid Range:   0,1,3,4,100-100000 (0=off, 1=dynamic, 3=dynamic conservative,
-                                   4=simplified balancing)
-Default Value: 3
-
-The driver can limit the amount of interrupts per second that the adapter
-will generate for incoming packets. It does this by writing a value to the
-adapter that is based on the maximum amount of interrupts that the adapter
-will generate per second.
-
-Setting InterruptThrottleRate to a value greater or equal to 100
-will program the adapter to send out a maximum of that many interrupts
-per second, even if more packets have come in. This reduces interrupt
-load on the system and can lower CPU utilization under heavy load,
-but will increase latency as packets are not processed as quickly.
-
-The driver has two adaptive modes (setting 1 or 3) in which
-it dynamically adjusts the InterruptThrottleRate value based on the traffic
-that it receives. After determining the type of incoming traffic in the last
-timeframe, it will adjust the InterruptThrottleRate to an appropriate value
-for that traffic.
-
-The algorithm classifies the incoming traffic every interval into
-classes.  Once the class is determined, the InterruptThrottleRate value is
-adjusted to suit that traffic type the best. There are three classes defined:
-"Bulk traffic", for large amounts of packets of normal size; "Low latency",
-for small amounts of traffic and/or a significant percentage of small
-packets; and "Lowest latency", for almost completely small packets or
-minimal traffic.
-
-In dynamic conservative mode, the InterruptThrottleRate value is set to 4000
-for traffic that falls in class "Bulk traffic". If traffic falls in the "Low
-latency" or "Lowest latency" class, the InterruptThrottleRate is increased
-stepwise to 20000. This default mode is suitable for most applications.
-
-For situations where low latency is vital such as cluster or
-grid computing, the algorithm can reduce latency even more when
-InterruptThrottleRate is set to mode 1. In this mode, which operates
-the same as mode 3, the InterruptThrottleRate will be increased stepwise to
-70000 for traffic in class "Lowest latency".
-
-In simplified mode the interrupt rate is based on the ratio of Tx and
-Rx traffic.  If the bytes per second rate is approximately equal the
-interrupt rate will drop as low as 2000 interrupts per second.  If the
-traffic is mostly transmit or mostly receive, the interrupt rate could
-be as high as 8000.
-
-Setting InterruptThrottleRate to 0 turns off any interrupt moderation
-and may improve small packet latency, but is generally not suitable
-for bulk throughput traffic.
-
-NOTE:  InterruptThrottleRate takes precedence over the TxAbsIntDelay and
-       RxAbsIntDelay parameters.  In other words, minimizing the receive
-       and/or transmit absolute delays does not force the controller to
-       generate more interrupts than what the Interrupt Throttle Rate
-       allows.
-
-NOTE:  When e1000e is loaded with default settings and multiple adapters
-       are in use simultaneously, the CPU utilization may increase non-
-       linearly.  In order to limit the CPU utilization without impacting
-       the overall throughput, we recommend that you load the driver as
-       follows:
-
-           modprobe e1000e InterruptThrottleRate=3000,3000,3000
-
-       This sets the InterruptThrottleRate to 3000 interrupts/sec for
-       the first, second, and third instances of the driver.  The range
-       of 2000 to 3000 interrupts per second works on a majority of
-       systems and is a good starting point, but the optimal value will
-       be platform-specific.  If CPU utilization is not a concern, use
-       RX_POLLING (NAPI) and default driver settings.
-
-RxIntDelay
-----------
-Valid Range:   0-65535 (0=off)
-Default Value: 0
-
-This value delays the generation of receive interrupts in units of 1.024
-microseconds.  Receive interrupt reduction can improve CPU efficiency if
-properly tuned for specific network traffic.  Increasing this value adds
-extra latency to frame reception and can end up decreasing the throughput
-of TCP traffic.  If the system is reporting dropped receives, this value
-may be set too high, causing the driver to run out of available receive
-descriptors.
-
-CAUTION:  When setting RxIntDelay to a value other than 0, adapters may
-          hang (stop transmitting) under certain network conditions.  If
-          this occurs a NETDEV WATCHDOG message is logged in the system
-          event log.  In addition, the controller is automatically reset,
-          restoring the network connection.  To eliminate the potential
-          for the hang ensure that RxIntDelay is set to 0.
-
-RxAbsIntDelay
--------------
-Valid Range:   0-65535 (0=off)
-Default Value: 8
-
-This value, in units of 1.024 microseconds, limits the delay in which a
-receive interrupt is generated.  Useful only if RxIntDelay is non-zero,
-this value ensures that an interrupt is generated after the initial
-packet is received within the set amount of time.  Proper tuning,
-along with RxIntDelay, may improve traffic throughput in specific network
-conditions.
-
-TxIntDelay
-----------
-Valid Range:   0-65535 (0=off)
-Default Value: 8
-
-This value delays the generation of transmit interrupts in units of
-1.024 microseconds.  Transmit interrupt reduction can improve CPU
-efficiency if properly tuned for specific network traffic.  If the
-system is reporting dropped transmits, this value may be set too high
-causing the driver to run out of available transmit descriptors.
-
-TxAbsIntDelay
--------------
-Valid Range:   0-65535 (0=off)
-Default Value: 32
-
-This value, in units of 1.024 microseconds, limits the delay in which a
-transmit interrupt is generated.  Useful only if TxIntDelay is non-zero,
-this value ensures that an interrupt is generated after the initial
-packet is sent on the wire within the set amount of time.  Proper tuning,
-along with TxIntDelay, may improve traffic throughput in specific
-network conditions.
-
-Copybreak
----------
-Valid Range:   0-xxxxxxx (0=off)
-Default Value: 256
-
-Driver copies all packets below or equaling this size to a fresh Rx
-buffer before handing it up the stack.
-
-This parameter is different than other parameters, in that it is a
-single (not 1,1,1 etc.) parameter applied to all driver instances and
-it is also available during runtime at
-/sys/module/e1000e/parameters/copybreak
-
-SmartPowerDownEnable
---------------------
-Valid Range: 0-1
-Default Value:  0 (disabled)
-
-Allows PHY to turn off in lower power states. The user can set this parameter
-in supported chipsets.
-
-KumeranLockLoss
----------------
-Valid Range: 0-1
-Default Value: 1 (enabled)
-
-This workaround skips resetting the PHY at shutdown for the initial
-silicon releases of ICH8 systems.
-
-IntMode
--------
-Valid Range: 0-2 (0=legacy, 1=MSI, 2=MSI-X)
-Default Value: 2
-
-Allows changing the interrupt mode at module load time, without requiring a
-recompile. If the driver load fails to enable a specific interrupt mode, the
-driver will try other interrupt modes, from least to most compatible.  The
-interrupt order is MSI-X, MSI, Legacy.  If specifying MSI (IntMode=1)
-interrupts, only MSI and Legacy will be attempted.
-
-CrcStripping
-------------
-Valid Range: 0-1
-Default Value: 1 (enabled)
-
-Strip the CRC from received packets before sending up the network stack.  If
-you have a machine with a BMC enabled but cannot receive IPMI traffic after
-loading or enabling the driver, try disabling this feature.
-
-WriteProtectNVM
----------------
-Valid Range: 0-1
-Default Value: 1 (enabled)
-
-Set the hardware to ignore all write/erase cycles to the GbE region in the
-ICHx NVM (non-volatile memory).  This feature can be disabled by the
-WriteProtectNVM module parameter (enabled by default) only after a hardware
-reset, but the machine must be power cycled before trying to enable writes.
-
-Note: the kernel boot option iomem=relaxed may need to be set if the kernel
-config option CONFIG_STRICT_DEVMEM=y, if the root user wants to write the
-NVM from user space via ethtool.
-
-Additional Configurations
-=========================
-
-  Jumbo Frames
-  ------------
-  Jumbo Frames support is enabled by changing the MTU to a value larger than
-  the default of 1500.  Use the ifconfig command to increase the MTU size.
-  For example:
-
-       ifconfig eth<x> mtu 9000 up
-
-  This setting is not saved across reboots.
-
-  Notes:
-
-  - The maximum MTU setting for Jumbo Frames is 9216.  This value coincides
-    with the maximum Jumbo Frames size of 9234 bytes.
-
-  - Using Jumbo Frames at 10 or 100 Mbps is not supported and may result in
-    poor performance or loss of link.
-
-  - Some adapters limit Jumbo Frames sized packets to a maximum of
-    4096 bytes and some adapters do not support Jumbo Frames.
-
-
-  Ethtool
-  -------
-  The driver utilizes the ethtool interface for driver configuration and
-  diagnostics, as well as displaying statistical information.  We
-  strongly recommend downloading the latest version of Ethtool at:
-
-  http://sourceforge.net/projects/gkernel.
-
-  Speed and Duplex
-  ----------------
-  Speed and Duplex are configured through the Ethtool* utility. For
-  instructions,  refer to the Ethtool man page.
-
-  Enabling Wake on LAN* (WoL)
-  ---------------------------
-  WoL is configured through the Ethtool* utility. For instructions on
-  enabling WoL with Ethtool, refer to the Ethtool man page.
-
-  WoL will be enabled on the system during the next shut down or reboot.
-  For this driver version, in order to enable WoL, the e1000e driver must be
-  loaded when shutting down or rebooting the system.
-
-  In most cases Wake On LAN is only supported on port A for multiple port
-  adapters. To verify if a port supports Wake on LAN run ethtool eth<X>.

-Concurrency Managed Workqueue (cmwq)

-CONTENTS
-
-1. Introduction
-2. Why cmwq?
-3. The Design
-4. Application Programming Interface (API)
-5. Example Execution Scenarios
-6. Guidelines
-
-
-1. Introduction
-
-There are many cases where an asynchronous process execution context
-is needed and the workqueue (wq) API is the most commonly used
-mechanism for such cases.
-
-When such an asynchronous execution context is needed, a work item
-describing which function to execute is put on a queue.  An
-independent thread serves as the asynchronous execution context.  The
-queue is called workqueue and the thread is called worker.
-
-While there are work items on the workqueue the worker executes the
-functions associated with the work items one after the other.  When
-there is no work item left on the workqueue the worker becomes idle.
-When a new work item gets queued, the worker begins executing again.
-
-
-2. Why cmwq?
-
-In the original wq implementation, a multi threaded (MT) wq had one
-worker thread per CPU and a single threaded (ST) wq had one worker
-thread system-wide.  A single MT wq needed to keep around the same
-number of workers as the number of CPUs.  The kernel grew a lot of MT
-wq users over the years and with the number of CPU cores continuously
-rising, some systems saturated the default 32k PID space just booting
-up.
-
-Although MT wq wasted a lot of resource, the level of concurrency
-provided was unsatisfactory.  The limitation was common to both ST and
-MT wq albeit less severe on MT.  Each wq maintained its own separate
-worker pool.  A MT wq could provide only one execution context per CPU
-while a ST wq one for the whole system.  Work items had to compete for
-those very limited execution contexts leading to various problems
-including proneness to deadlocks around the single execution context.
-
-The tension between the provided level of concurrency and resource
-usage also forced its users to make unnecessary tradeoffs like libata
-choosing to use ST wq for polling PIOs and accepting an unnecessary
-limitation that no two polling PIOs can progress at the same time.  As
-MT wq don't provide much better concurrency, users which require
-higher level of concurrency, like async or fscache, had to implement
-their own thread pool.
-
-Concurrency Managed Workqueue (cmwq) is a reimplementation of wq with
-focus on the following goals.
-
-* Maintain compatibility with the original workqueue API.
-
-* Use per-CPU unified worker pools shared by all wq to provide
-  flexible level of concurrency on demand without wasting a lot of
-  resource.
-
-* Automatically regulate worker pool and level of concurrency so that
-  the API users don't need to worry about such details.
-
-
-3. The Design
-
-In order to ease the asynchronous execution of functions a new
-abstraction, the work item, is introduced.
-
-A work item is a simple struct that holds a pointer to the function
-that is to be executed asynchronously.  Whenever a driver or subsystem
-wants a function to be executed asynchronously it has to set up a work
-item pointing to that function and queue that work item on a
-workqueue.
-
-Special purpose threads, called worker threads, execute the functions
-off of the queue, one after the other.  If no work is queued, the
-worker threads become idle.  These worker threads are managed in so
-called thread-pools.
-
-The cmwq design differentiates between the user-facing workqueues that
-subsystems and drivers queue work items on and the backend mechanism
-which manages thread-pool and processes the queued work items.
-
-The backend is called gcwq.  There is one gcwq for each possible CPU
-and one gcwq to serve work items queued on unbound workqueues.
-
-Subsystems and drivers can create and queue work items through special
-workqueue API functions as they see fit. They can influence some
-aspects of the way the work items are executed by setting flags on the
-workqueue they are putting the work item on. These flags include
-things like CPU locality, reentrancy, concurrency limits and more. To
-get a detailed overview refer to the API description of
-alloc_workqueue() below.
-
-When a work item is queued to a workqueue, the target gcwq is
-determined according to the queue parameters and workqueue attributes
-and appended on the shared worklist of the gcwq.  For example, unless
-specifically overridden, a work item of a bound workqueue will be
-queued on the worklist of exactly that gcwq that is associated to the
-CPU the issuer is running on.
-
-For any worker pool implementation, managing the concurrency level
-(how many execution contexts are active) is an important issue.  cmwq
-tries to keep the concurrency at a minimal but sufficient level.
-Minimal to save resources and sufficient in that the system is used at
-its full capacity.
-
-Each gcwq bound to an actual CPU implements concurrency management by
-hooking into the scheduler.  The gcwq is notified whenever an active
-worker wakes up or sleeps and keeps track of the number of the
-currently runnable workers.  Generally, work items are not expected to
-hog a CPU and consume many cycles.  That means maintaining just enough
-concurrency to prevent work processing from stalling should be
-optimal.  As long as there are one or more runnable workers on the
-CPU, the gcwq doesn't start execution of a new work, but, when the
-last running worker goes to sleep, it immediately schedules a new
-worker so that the CPU doesn't sit idle while there are pending work
-items.  This allows using a minimal number of workers without losing
-execution bandwidth.
-
-Keeping idle workers around doesn't cost other than the memory space
-for kthreads, so cmwq holds onto idle ones for a while before killing
-them.
-
-For an unbound wq, the above concurrency management doesn't apply and
-the gcwq for the pseudo unbound CPU tries to start executing all work
-items as soon as possible.  The responsibility of regulating
-concurrency level is on the users.  There is also a flag to mark a
-bound wq to ignore the concurrency management.  Please refer to the
-API section for details.
-
-Forward progress guarantee relies on that workers can be created when
-more execution contexts are necessary, which in turn is guaranteed
-through the use of rescue workers.  All work items which might be used
-on code paths that handle memory reclaim are required to be queued on
-wq's that have a rescue-worker reserved for execution under memory
-pressure.  Else it is possible that the thread-pool deadlocks waiting
-for execution contexts to free up.
-
-
-4. Application Programming Interface (API)
-
-alloc_workqueue() allocates a wq.  The original create_*workqueue()
-functions are deprecated and scheduled for removal.  alloc_workqueue()
-takes three arguments - @name, @flags and @max_active.  @name is the
-name of the wq and also used as the name of the rescuer thread if
-there is one.
-
-A wq no longer manages execution resources but serves as a domain for
-forward progress guarantee, flush and work item attributes.  @flags
-and @max_active control how work items are assigned execution
-resources, scheduled and executed.
-
-@flags:
-
-  WQ_NON_REENTRANT
-
-	By default, a wq guarantees non-reentrance only on the same
-	CPU.  A work item may not be executed concurrently on the same
-	CPU by multiple workers but is allowed to be executed
-	concurrently on multiple CPUs.  This flag makes sure
-	non-reentrance is enforced across all CPUs.  Work items queued
-	to a non-reentrant wq are guaranteed to be executed by at most
-	one worker system-wide at any given time.
-
-  WQ_UNBOUND
-
-	Work items queued to an unbound wq are served by a special
-	gcwq which hosts workers which are not bound to any specific
-	CPU.  This makes the wq behave as a simple execution context
-	provider without concurrency management.  The unbound gcwq
-	tries to start execution of work items as soon as possible.
-	Unbound wq sacrifices locality but is useful for the following
-	cases.
-
-	* Wide fluctuation in the concurrency level requirement is
-	  expected and using bound wq may end up creating large number
-	  of mostly unused workers across different CPUs as the issuer
-	  hops through different CPUs.
-
-	* Long running CPU intensive workloads which can be better
-	  managed by the system scheduler.
-
-  WQ_FREEZEABLE
-
-	A freezeable wq participates in the freeze phase of the system
-	suspend operations.  Work items on the wq are drained and no
-	new work item starts execution until thawed.
-
-  WQ_RESCUER
-
-	All wq which might be used in the memory reclaim paths _MUST_
-	have this flag set.  This reserves one worker exclusively for
-	the execution of this wq under memory pressure.
-
-  WQ_HIGHPRI
-
-	Work items of a highpri wq are queued at the head of the
-	worklist of the target gcwq and start execution regardless of
-	the current concurrency level.  In other words, highpri work
-	items will always start execution as soon as execution
-	resource is available.
-
-	Ordering among highpri work items is preserved - a highpri
-	work item queued after another highpri work item will start
-	execution after the earlier highpri work item starts.
-
-	Although highpri work items are not held back by other
-	runnable work items, they still contribute to the concurrency
-	level.  Highpri work items in runnable state will prevent
-	non-highpri work items from starting execution.
-
-	This flag is meaningless for unbound wq.
-
-  WQ_CPU_INTENSIVE
-
-	Work items of a CPU intensive wq do not contribute to the
-	concurrency level.  In other words, runnable CPU intensive
-	work items will not prevent other work items from starting
-	execution.  This is useful for bound work items which are
-	expected to hog CPU cycles so that their execution is
-	regulated by the system scheduler.
-
-	Although CPU intensive work items don't contribute to the
-	concurrency level, start of their executions is still
-	regulated by the concurrency management and runnable
-	non-CPU-intensive work items can delay execution of CPU
-	intensive work items.
-
-	This flag is meaningless for unbound wq.
-
-  WQ_HIGHPRI | WQ_CPU_INTENSIVE
-
-	This combination makes the wq avoid interaction with
-	concurrency management completely and behave as a simple
-	per-CPU execution context provider.  Work items queued on a
-	highpri CPU-intensive wq start execution as soon as resources
-	are available and don't affect execution of other work items.
-
-@max_active:
-
-@max_active determines the maximum number of execution contexts per
-CPU which can be assigned to the work items of a wq.  For example,
-with @max_active of 16, at most 16 work items of the wq can be
-executing at the same time per CPU.
-
-Currently, for a bound wq, the maximum limit for @max_active is 512
-and the default value used when 0 is specified is 256.  For an unbound
-wq, the limit is higher of 512 and 4 * num_possible_cpus().  These
-values are chosen sufficiently high such that they are not the
-limiting factor while providing protection in runaway cases.
-
-The number of active work items of a wq is usually regulated by the
-users of the wq, more specifically, by how many work items the users
-may queue at the same time.  Unless there is a specific need for
-throttling the number of active work items, specifying '0' is
-recommended.
-
-Some users depend on the strict execution ordering of ST wq.  The
-combination of @max_active of 1 and WQ_UNBOUND is used to achieve this
-behavior.  Work items on such wq are always queued to the unbound gcwq
-and only one work item can be active at any given time thus achieving
-the same ordering property as ST wq.
-
-
-5. Example Execution Scenarios
-
-The following example execution scenarios try to illustrate how cmwq
-behave under different configurations.
-
- Work items w0, w1, w2 are queued to a bound wq q0 on the same CPU.
- w0 burns CPU for 5ms then sleeps for 10ms then burns CPU for 5ms
- again before finishing.  w1 and w2 burn CPU for 5ms then sleep for
- 10ms.
-
-Ignoring all other tasks, works and processing overhead, and assuming
-simple FIFO scheduling, the following is one highly simplified version
-of possible sequences of events with the original wq.
-
- TIME IN MSECS	EVENT
- 0		w0 starts and burns CPU
- 5		w0 sleeps
- 15		w0 wakes up and burns CPU
- 20		w0 finishes
- 20		w1 starts and burns CPU
- 25		w1 sleeps
- 35		w1 wakes up and finishes
- 35		w2 starts and burns CPU
- 40		w2 sleeps
- 50		w2 wakes up and finishes
-
-And with cmwq with @max_active >= 3,
-
- TIME IN MSECS	EVENT
- 0		w0 starts and burns CPU
- 5		w0 sleeps
- 5		w1 starts and burns CPU
- 10		w1 sleeps
- 10		w2 starts and burns CPU
- 15		w2 sleeps
- 15		w0 wakes up and burns CPU
- 20		w0 finishes
- 20		w1 wakes up and finishes
- 25		w2 wakes up and finishes
-
-If @max_active == 2,
-
- TIME IN MSECS	EVENT
- 0		w0 starts and burns CPU
- 5		w0 sleeps
- 5		w1 starts and burns CPU
- 10		w1 sleeps
- 15		w0 wakes up and burns CPU
- 20		w0 finishes
- 20		w1 wakes up and finishes
- 20		w2 starts and burns CPU
- 25		w2 sleeps
- 35		w2 wakes up and finishes
-
-Now, let's assume w1 and w2 are queued to a different wq q1 which has
-WQ_HIGHPRI set,
-
- TIME IN MSECS	EVENT
- 0		w1 and w2 start and burn CPU
- 5		w1 sleeps
- 10		w2 sleeps
- 10		w0 starts and burns CPU
- 15		w0 sleeps
- 15		w1 wakes up and finishes
- 20		w2 wakes up and finishes
- 25		w0 wakes up and burns CPU
- 30		w0 finishes
-
-If q1 has WQ_CPU_INTENSIVE set,
-
- TIME IN MSECS	EVENT
- 0		w0 starts and burns CPU
- 5		w0 sleeps
- 5		w1 and w2 start and burn CPU
- 10		w1 sleeps
- 15		w2 sleeps
- 15		w0 wakes up and burns CPU
- 20		w0 finishes
- 20		w1 wakes up and finishes
- 25		w2 wakes up and finishes
-
-
-6. Guidelines
-
-* Do not forget to use WQ_RESCUER if a wq may process work items which
-  are used during memory reclaim.  Each wq with WQ_RESCUER set has one
-  rescuer thread reserved for it.  If there is dependency among
-  multiple work items used during memory reclaim, they should be
-  queued to separate wq each with WQ_RESCUER.
-
-* Unless strict ordering is required, there is no need to use ST wq.
-
-* Unless there is a specific need, using 0 for @max_active is
-  recommended.  In most use cases, concurrency level usually stays
-  well under the default limit.
-
-* A wq serves as a domain for forward progress guarantee (WQ_RESCUER),
-  flush and work item attributes.  Work items which are not involved
-  in memory reclaim and don't need to be flushed as a part of a group
-  of work items, and don't require any special attribute, can use one
-  of the system wq.  There is no difference in execution
-  characteristics between using a dedicated wq and a system wq.
-
-* Unless work items are expected to consume a huge amount of CPU
-  cycles, using a bound wq is usually beneficial due to the increased
-  level of locality in wq operations and work item execution.
