Hi all, here are some patches for PRLI issues in libfc we've come across recently. The libfc ones are pretty straightforward, but the scsi state machine one probably warrants some discussion. What happened was that in some fabrics the RSCN might get lost or incompletely reseived. This will then cause SCSI EH to be triggered for the lost rports, setting the devices to offline. But later on we do get an RSCN, which would reinstate the rports, but unfortunately the devices will remain in OFFLINE as we cannot transition back to running. The solution I've came up with was to allow transitions from OFFLINE to BLOCKED, as during RSCN processing the devices will be set to blocked, and so I found it only reasonable to allow this transition. But as usual, comments and reviews are welcome.
