Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull final round of SCSI updates from James Bottomley:
"This is primarily another round of driver updates (bnx2fc, qla2xxx,
qla4xxx) including the target mode driver for qla2xxx. We've also got
a couple of regression fixes (async scanning, broken this merge window
and a fix to a long standing break in the scsi_wait_scan module)."

[SCSI] fix scsi_wait_scan
[SCSI] fix async probe regression
[SCSI] be2iscsi: fix dma free size mismatch regression
[SCSI] qla4xxx: Update driver version to 5.02.00-k17
[SCSI] qla4xxx: Capture minidump for ISP82XX on firmware failure
[SCSI] qla4xxx: Add change_queue_depth API support
[SCSI] qla4xxx: Fix clear ddb mbx command failure issue.
[SCSI] qla4xxx: Fix kernel panic during discovery logout.
[SCSI] qla4xxx: Correct early completion of pending mbox.
[SCSI] fcoe, bnx2fc, libfcoe: SW FCoE and bnx2fc use FCoE Syfs
[SCSI] libfcoe: Add fcoe_sysfs

+Date:		March 2012
+KernelVersion:	TBD
+Contact:	Robert Love <[e-mail]>, [e-mail]
+Description:	'FCoE FCF' instances on the fcoe bus. A FCF is a Fibre Channel
+		Forwarder, which is a FCoE switch that can accept FCoE
+		(Ethernet) packets, unpack them, and forward the embedded
+		Fibre Channel frames into a FC fabric. It can also take
+		outbound FC frames and pack them in Ethernet packets to
+		be sent to their destination on the Ethernet segment.
+Attributes:
+
+	fabric_name: Identifies the fabric that the FCF services.
+
+	switch_name: Identifies the FCF.
+
+	priority:    The switch's priority amongst other FCFs on the same
+		     fabric.
+
+	selected:    1 indicates that the switch has been selected for use;
+		     0 indicates that the swich will not be used.
+
+	fc_map:      The Fibre Channel MAP
+
+	vfid:	     The Virtual Fabric ID
+
+	mac:         The FCF's MAC address
+
+	fka_peroid:  The FIP Keep-Alive peroid
+
+	fabric_state: The internal kernel state
+		      "Unknown" - Initialization value
+		      "Disconnected" - No link to the FCF/fabric
+		      "Connected" - Host is connected to the FCF
+		      "Deleted" - FCF is being removed from the system
+
+	dev_loss_tmo: The device loss timeout peroid for this FCF.
+
+Notes: A device loss infrastructre similar to the FC Transport's
+       is present in fcoe_sysfs. It is nice to have so that a
+       link flapping adapter doesn't continually advance the count
+       used to identify the discovered FCF. FCFs will exist in a
+       "Disconnected" state until either the timer expires and the
+       FCF becomes "Deleted" or the FCF is rediscovered and becomes
+       "Connected."
+
+
+Users: The first user of this interface will be the fcoeadm application,
+       which is commonly packaged in the fcoe-utils package.
