[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)
