+Date:		January 2, 2006
+KernelVersion:	2.6.15
+Contact:	linux-rdma@vger.kernel.org
+Description:	Interface for making ib_srp connect to a new target.
+		One can request ib_srp to connect to a new target by writing
+		a comma-separated list of login parameters to this sysfs
+		attribute. The supported parameters are:
+		* id_ext, a 16-digit hexadecimal number specifying the eight
+		  byte identifier extension in the 16-byte SRP target port
+		  identifier. The target port identifier is sent by ib_srp
+		  to the target in the SRP_LOGIN_REQ request.
+		* ioc_guid, a 16-digit hexadecimal number specifying the eight
+		  byte I/O controller GUID portion of the 16-byte target port
+		  identifier.
+		* dgid, a 32-digit hexadecimal number specifying the
+		  destination GID.
+		* pkey, a four-digit hexadecimal number specifying the
+		  InfiniBand partition key.
+		* service_id, a 16-digit hexadecimal number specifying the
+		  InfiniBand service ID used to establish communication with
+		  the SRP target. How to find out the value of the service ID
+		  is specified in the documentation of the SRP target.
+		* max_sect, a decimal number specifying the maximum number of
+		  512-byte sectors to be transferred via a single SCSI command.
+		* max_cmd_per_lun, a decimal number specifying the maximum
+		  number of outstanding commands for a single LUN.
+		* io_class, a hexadecimal number specifying the SRP I/O class.
+		  Must be either 0xff00 (rev 10) or 0x0100 (rev 16a). The I/O
+		  class defines the format of the SRP initiator and target
+		  port identifiers.
+		* initiator_ext, a 16-digit hexadecimal number specifying the
+		  identifier extension portion of the SRP initiator port
+		  identifier. This data is sent by the initiator to the target
+		  in the SRP_LOGIN_REQ request.
+		* cmd_sg_entries, a number in the range 1..255 that specifies
+		  the maximum number of data buffer descriptors stored in the
+		  SRP_CMD information unit itself. With allow_ext_sg=0 the
+		  parameter cmd_sg_entries defines the maximum S/G list length
+		  for a single SRP_CMD, and commands whose S/G list length
+		  exceeds this limit after S/G list collapsing will fail.
+		* allow_ext_sg, whether ib_srp is allowed to include a partial
+		  memory descriptor list in an SRP_CMD instead of the entire
+		  list. If a partial memory descriptor list has been included
+		  in an SRP_CMD the remaining memory descriptors are
+		  communicated from initiator to target via an additional RDMA
+		  transfer. Setting allow_ext_sg to 1 increases the maximum
+		  amount of data that can be transferred between initiator and
+		  target via a single SCSI command. Since not all SRP target
+		  implementations support partial memory descriptor lists the
+		  default value for this option is 0.
+		* sg_tablesize, a number in the range 1..2048 specifying the
+		  maximum S/G list length the SCSI layer is allowed to pass to
+		  ib_srp. Specifying a value that exceeds cmd_sg_entries is
+		  only safe with partial memory descriptor list support enabled
+		  (allow_ext_sg=1).

+		Userspace applications can read and write to this file to
+		determine and control the enablement or disablement of Virtual
+		Functions (VFs) on the physical function (PF). A read of this
+		file will return the number of VFs that are enabled on this PF.
+		A number written to this file will enable the specified
+		number of VFs. A userspace application would typically read the
+		file and check that the value is zero, and then write the number
+		of VFs that should be enabled on the PF; the value written
+		should be less than or equal to the value in the sriov_totalvfs
+		file. A userspace application wanting to disable the VFs would
+		write a zero to this file. The core ensures that valid values
+		are written to this file, and returns errors when values are not
+		valid.  For example, writing a 2 to this file when sriov_numvfs
+		is not 0 and not 2 already will return an error. Writing a 10
+		when the value of sriov_totalvfs is 8 will return an error.
