2018-02-13scsi: qedf: remove redundant initialization of 'fcport'Colin Ian King
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 Signed-off-by: Colin Ian King <colin.king@canonical.com> Acked-by: Chad Dupuis <chad.dupuis@cavium.com> Signed-off-by: Martin K.

2018-01-02qed*: Utilize FW 8.33.1.0Tomer Tayar
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.

2017-03-13qed*: Utilize Firmware 8.15.3.0Mintz, Yuval
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].

2017-02-23scsi: qedf: fixup compilation warning about atomic_t usageDupuis, Chad
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.
