Subject: [PATCH 01/78] netdevice libertas: Fix directly reference of
 netdev->priv

We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug",
and I want to kill netdev->priv later, I decided to convert all the direct
reference of netdev->priv first.

Different to readonly reference of netdev->priv, in this driver, netdev->priv
was changed. I use netdev->ml_priv to replace netdev->priv.

Subject: [PATCH 02/78] p54: introduce new names for device firmwares

Johannes thought it would have been a good idea to change the firmware names.

Note: we still have fallbacks in case our users don't want to "break their running system",
but we won't advertise them with MODULE_FIRMWARE.

Subject: [PATCH 03/78] p54: more definitions form lmac_longbow.h and pda.h

This patch ports more useful features to p54
  - PDR definitions for the synth chips & regulatory domain.
  - honour IEEE80211_TX_CTL_ASSIGN_SEQ flag, if it's set.
  - adds some lost mutex_lock & mutex_unlock.
  - replace two more "magic values" that sneaked past.

Subject: [PATCH 12/78] iwlwifi: remove implicit direct scan

When an undirected scan is requested and iwlwifi is not associated but
the user has set an SSID (and maybe was associated with that network at
some point) then iwlwifi will assume the user wanted to scan for this
SSID which seems wrong. Remove this code.

Subject: [PATCH 14/78] b43/legacy: remove SSID code

The SSID programmed into the device is used by the ucode only
to reply to probe requests, a functionality we disable anyway
because it doesn't fit with the mac80211/hostapd programming
model. Therefore, it isn't useful to program the SSID into
device.

Since adm8211 currently doesn't implement IBSS mode anyway,
it can't be using the SSID. And if/when it does implement
IBSS mode, we'll have to see how to make it beacon anyway.

Subject: [PATCH 16/78] mac80211: remove SSID driver code

Remove the SSID from the driver API since now there is no
driver that requires knowing the SSID and I think it's
unlikely that any hardware design that does require the
SSID will play well with mac80211.

This also removes support for setting the SSID in master
mode which will require a patch to hostapd to not try.

Subject: [PATCH 17/78] iwl3945: remove bogus comment

I added this comment myself, but it's clearly wrong. I had meant
to place it in iwl_mac_add_interface, which at the time didn't
honour the MAC address setting, but it does now.

Subject: [PATCH 18/78] don't use net/ieee80211.h

Convert all the drivers using net/ieee80211.h to use linux/ieee80211.h.
Contains a bugfix in libertas where the SSID parsing could overrun the
buffer when the AP sends invalid information.

Subject: [PATCH 19/78] ath5k: Update PCU code

* In set_opmode don't handle antenna settings and preserve other STA_ID1 settings
(shouldn't matter because we call it during reset but it makes things cleaner)
Also set properly AP/ADHOC indicator flag on CFG while setting AP/ADHOC modes
and always enable key search mode.

* Properly set BSSID Mask during reset (cache it and reuse it durring set_associd)

* Update beacon_init to flush pending BMISS interrupts and handle setting of adhoc
beacon ATIM policy flag for ad-hoc mode. Also set TSF to 0 to start TSF increment
on AP mode. We need to handle sleep timers for AR5212 there + add support for PCF.

* Properly clean MIC key from keytable when TKIP is used (Bob is working on set_key
function etc so i leave it for now).

Tested on AR5212 (Hainan) and AR5413 and works fine

v2 Set PISR on AR5211+ and ISR on AR5210, got to sleep more ;-)

Subject: [PATCH 40/78] rt2x00: Optimize configuration handling

Implement latest changed from mac80211 configuration
handling to optmize configuration handling in rt2x00.

 * Remove set_retry_limit callback function, handled
   through config()
 * Move config_antenna to its own callback function,
   it isn't handled by mac80211 anymore
 * Use IEEE80211_CONF_CHANGED_* flags and remove manual
   checks
 * Removed deprecated short slot setting through config()
   and put it in config_erp() through which mac80211 now
   configures it
 * Remove config_phymode() and move contents to config_erp()
   since it only managed the basic rates which is now
   determined by mac80211 through config_erp().

Subject: [PATCH 41/78] rt2x00: Remove ieee80211_bss_conf from rt2x00_intf

We can safely remove ieee80211_bss_conf from rt2x00_intf,
it is provided by mac80211 in ieee80211_vif as well.
(rt2x00_intf is the drv_priv field of ieee80211_vif).

Subject: [PATCH 45/78] rtl8187: Remove OFDM delays

Routine rtl8225_write_phy_ofdm() calls rtl8225_write_phy(), which concludes
with a sleep of 1 msec; therefore a call to rtl8225_write_phy_ofdm()
immediately followed by an msleep(1) is not needed.

Subject: [PATCH 47/78] rtl8187: Remove msleep calls after calls to
 rtl8225_write

Routine rtl8225_write() calls either rtl8225_write_bitbang() or
rtl8225_write_8051(), both of which end with an msleep() command. As a
result, a rtl8225_write() immediately followed by an msleep() is not needed.

Each of the primary write routines, rtl8187_write_phy(),
rtl8225_write_bitbang(), and rtl8225_write_8051() all conclude with an
msleep() command. Testing shows that these are not needed.

Subject: [PATCH 49/78] rtl8187: Reduce channel switch delay

The latest vendor driver (rtl8187B_linux_26.1036.0708.2008) has a 10 msec
delay after the call to set a new channel, but not before.

Subject: [PATCH 51/78] rt2x00: Remove debugfs CSR access wrappers

Move calculation of CSR register offset into rt2x00debug.c
and remove the wrapper functions from each individual driver.
(Except rt2500usb, which still needs to wrap for the
different value type argument).

Subject: [PATCH 56/78] iwlwifi: fix priv->iw_mode setting when multiple vif
 are configured

mac80211 supports multiple virtual interfaces for a single device. For
example, a managed interface (wlan0) and a monitor interface (mon0) can
exist at the same time. Thus priv->iw_mode is not sufficient to track
the wireless mode any more. The patch redefines priv->iw_mode as the
first interface mode (the same as priv->vif->type if priv->vif != NULL).
If another monitor type interface is created later, we don't change
priv->iw_mode into monitor. This way, the original interface still
works. The patch also requests mac80211 to do reassociation after we
change the Rx filter flags.

Subject: [PATCH 68/78] nl80211: Add TX queue parameter configuration

Add a new attribute, NL80211_ATTR_WIPHY_TXQ_PARAMS, that can be used with
NL80211_CMD_SET_WIPHY for userspace (e.g., hostapd) to set TX queue
parameters (txop, cwmin, cwmax, aifs).

Subject: [PATCH 71/78] mac80211: Allow AP mode to be enabled

With the addition of basic rate set and TX queue parameter
configuration and confirmation that power save buffering is
working again, mac80211 is now in state that allows AP mode to be
used without major problems. Consequently, it is time to allow this
mode to be enabled without having to patch the kernel.

AP mode requires hostapd for management frame processing and as such,
configuring this mode is only allowed through cfg80211 (not with
iwconfig and WEXT).

Subject: [PATCH 72/78] mac80211_hwsim: Add support for client PS mode

This introduces a debugfs file (ieee80211/phy#/hwsim/ps) that can be
used to force a simulated radio into power save mode. Following values
can be written into this file to change PS mode:
0 = power save disabled (constantly awake)
1 = power save enabled (drop all frames; do not send PS-Poll)
2 = power save enabled (send PS-Poll frames automatically to receive
    buffered unicast frames); not yet fully implemented
3 = manual PS-Poll trigger (send a single PS-Poll frame)

Two different behavior for power save mode processing can be tested:
- move between modes 1 and 0 (i.e., receive all buffered frames at a
  time)
- move to mode 1 and use manual PS-Poll frames (write 3 to the 'ps'
  debugfs file) to fetch power save buffered frames one at a time

Mode 2 (automatic PS-Poll) does not yet parse Beacon frames, but
eventually, it should take a look at TIM IE and send PS-Poll if a
traffic bit is set for our AID.

Subject: [PATCH 74/78] cfg80211: Add regulatory domain intersection capability

There are certain scenerios where we require intersecting
two regulatory domains. This adds intersection support.
When we enable 802.11d support we will use this to intersect
the regulatory domain from the AP's country IE and what our
regulatory agent believes is correct for a country.

This patch enables intersection for now in the case where
the last regdomain was set by a country IE which was parsed
and the user then wants to set the regulatory domain. Since
we don't support country IE parsing yet this code path will not
be hit, however this allows us to pave the way for 11d support.

Intersection code has been tested in userspace with CRDA.

Subject: [PATCH 76/78] cfg80211: Add kdoc for struct regulatory_request

As regulatory_request gets bigger there will be more questions
of what things means, so clarify documenation for it and
keep track of the special alpha2 codes we use internally
and on the userspace regulatory agents.
