[SCSI] lpfc 8.3.21: FC Discovery changes
FC Discovery changes
- Treat received PLOGI while logged in as a relogin (unregister and reregister).
- Added a timer to delay Nport discovery when clean bit is cleared and Fabric
portname/nodename/FCID is changed.
- Invalidate Port's DID when receiving PLOGI from p2p port with CONFIG_PORT
mailbox command.
