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. Reported-by: kernel test robot <lkp@xxxxxxxxx> Closes: https://lore.kernel.org/oe-kbuild-all/202406110734.p2v8dq9v-lkp @intel.com/ Reviewed-by: Sesidhar Baddela <sebaddel@xxxxxxxxx> Co-developed-by: Gian Carlo Boffa <gcboffa@xxxxxxxxx> Signed-off-by: Gian Carlo Boffa <gcboffa@xxxxxxxxx> Co-developed-by: Arulprabhu Ponnusamy <arulponn@xxxxxxxxx> Signed-off-by: Arulprabhu Ponnusamy <arulponn@xxxxxxxxx> Co-developed-by: Arun Easi <aeasi@xxxxxxxxx> Signed-off-by: Arun Easi <aeasi@xxxxxxxxx> Co-developed-by: Karan Tilak Kumar <kartilak@xxxxxxxxx> Signed-off-by: Karan Tilak Kumar <kartilak@xxxxxxxxx> --- 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.
