Subject: [PATCH v5 06/14] scsi: fnic: Add and integrate support for FDMI
Add support for Fabric-Device Management Interface
(FDMI) by introducing PCI device IDs for Cisco
Hardware.
Introduce a module parameter to enable/disable
FDMI support.
Integrate support for FDMI.

Changes between v4 and v5:
Incorporate review comments from Martin:
Modify attribution appropriately.
Remove spurious newline at the end of fdls_disc.c.
Remove spurious newline at the end of fnic_main.c.
Changes between v2 and v3:
Incorporate review comments from Hannes:
Replace redundant definitions with standard definitions.
Changes between v1 and v2:
Incorporate review comments from Hannes from other patches:
Replace pr_info with dev_info.
Replace htonll() with get_unaligned_be64().
Replace definitions with standard definitions from fc_els.h.
Use standard definitions from scsi_transport_fc.h for
port speeds.
Refactor definitions in struct fnic to avoid cache holes.
Replace memcmp with not equal to operator.
Fix warning from kernel test robot:
Remove version.h
