Subject: [PATCH] scsi: scsi_transport_fc: Add FPIN fc event codes
References: bsc#1136217,jsc#SLE-4722
Git-commit: c39e0af64bce3bba61c3986d6083df7b8f29a310
Patch-mainline: v5.2-rc1
Add a new event type - an FPIN event.
Add a new routine, fc_host_fpin_rcv(), that lldd's call when an FPIN is
received. The routine processes the fpin payload. For now, the routine
only logs an FPIN event.
