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)."

+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.
