Colin Ian King 8d6febb0cc scsi: qedf: remove redundant initialization of 'fcport'
Pointer fcport is initialized with a value that is never read, it is
re-assigned a new value later on, hence the initialization is redundant
and can be removed.

Cleans up clang warning:
drivers/scsi/qedf/qedf_io.c:920:21: warning: Value stored to 'fcport'
during its initialization is never read

Tomer Tayar da09091732 qed*: Utilize FW 8.33.1.0
Advance the qed* drivers to use firmware 8.33.1.0:
Modify core driver (qed) to utilize the new FW and initialize the device
with it. This is the lion's share of the patch, and includes changes to FW
interface files, device initialization flows, FW interaction flows, and
debug collection flows.
Modify Ethernet driver (qede) to make use of new FW in fastpath.
Modify RoCE/iWARP driver (qedr) to make use of new FW in fastpath.
Modify FCoE driver (qedf) to make use of new FW in fastpath.
Modify iSCSI driver (qedi) to make use of new FW in fastpath.

Dupuis, Chad 16a611154d scsi: qedf: Check if sense buffer has been allocated during completion
sc_cmd->sense_buffer is not guaranteed to be allocated so we need to
sc_cmd->check
if the pointer is NULL before trying to copy anything into it.

Mintz, Yuval be086e7c53 qed*: Utilize Firmware 8.15.3.0
This patch advances the qed* drivers into using the newer firmware -
This solves several firmware bugs, mostly related [but not limited to]
various init/deinit issues in various offloaded protocols.

It also introduces a major 4-Cached SGE change in firmware, which can be
seen in the storage drivers' changes.

In addition, this firmware is required for supporting the new QL41xxx
series of adapters; While this patch doesn't add the actual support,
the firmware contains the necessary initialization & firmware logic to
operate such adapters [actual support would be added later on].

Changes from Previous versions:
-------------------------------
 - V2 - fix kbuild-test robot warnings

Dupuis, Chad 1afca6b5f3 scsi: qedf: fixup compilation warning about atomic_t usage
Based on an original patch by Hannes Reinecke.

The driver didn't follow the atomic_t vs refcount_t change, and anyway
one should be using kref_read() instead of accessing the counter inside
an kref.
