[SCSI] lpfc 8.3.28: SLI fixes and added SLI4 support
Adapter (SLI) interface fixes: - Modify WQ handling to use entry_repost (CR 123981) - Fix for ABTS. Do not free original IOCB whenever ABTS fails. (CR 115829) - Check board for FCoE before reading FCoE paramaters (CR124731) - Add support for SLI4 FC Loop mode (CR 124721) - Add support for resource count changes during fw reset. (CR 125888, 125675) - Increase CQE count from 256 to 1024. (CR 126149) Signed-off-by: Alex Iannicelli <alex.iannicelli@emulex.com> Signed-off-by: James Smart <james.smart@emulex.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
