This is an assorted set of stragglers into the merge window with driver
 updates for qla2xxx, megaraid_sas, storvsc and ufs.  It also includes pulls of
 the uapi tree (all the remaining SCSI pieces) and the fcoe tree (updates to
 fcoe and libfc)

Description: The FCoE bus. Attributes in this directory are control interfaces.
Attributes:
ctlr_create: 'FCoE Controller' instance creation interface. Writing an
<ifname> to this file will allocate and populate sysfs with a
fcoe_ctlr_device (ctlr_X). The user can then configure any
per-port settings and finally write to the fcoe_ctlr_device's
'start' attribute to begin the kernel's discovery and login
process.
ctlr_destroy: 'FCoE Controller' instance removal interface. Writing a
fcoe_ctlr_device's sysfs name to this file will log the
fcoe_ctlr_device out of the fabric or otherwise connected
FCoE devices. It will also free all kernel memory allocated
for this fcoe_ctlr_device and any structures associated
with it, this includes the scsi_host.

Description: 'FCoE Controller' instances on the fcoe bus
Description: 'FCoE Controller' instances on the fcoe bus.
The FCoE Controller now has a three stage creation process.
1) Write interface name to ctlr_create 2) Configure the FCoE
Controller (ctlr_X) 3) Enable the FCoE Controller to begin
discovery and login. The FCoE Controller is destroyed by
writing it's name, i.e. ctlr_X to the ctlr_delete file.
Attributes:
fcf_dev_loss_tmo: Device loss timeout peroid (see below). Changing
this value will change the dev_loss_tmo for all
FCFs discovered by this controller.
mode: Display or change the FCoE Controller's mode. Possible
modes are 'Fabric' and 'VN2VN'. If a FCoE Controller
is started in 'Fabric' mode then FIP FCF discovery is
initiated and ultimately a fabric login is attempted.
If a FCoE Controller is started in 'VN2VN' mode then
FIP VN2VN discovery and login is performed. A FCoE
Controller only supports one mode at a time.
enabled: Whether an FCoE controller is enabled or disabled.
0 if disabled, 1 if enabled. Writing either 0 or 1
to this file will enable or disable the FCoE controller.
lesb/link_fail: Link Error Status Block (LESB) link failure count.
lesb/vlink_fail: Link Error Status Block (LESB) virtual link
