When connected point to point, the driver does not know the FC4's supported by the other end. In Fabrics, it can query the nameserver. Thus the driver must send PRLIs for the FC4s it supports and enable support based on the acc(ept) or rej(ect) of the respective FC4 PRLI. Currently the driver supports SCSI and NVMe PRLIs. Unfortunately, although the behavior is per standard, many devices have come to expect only SCSI PRLIs. In this particular example, the NVMe PRLI is properly RJT'd but the target decided that it must LOGO after seeing the unexpected NVMe PRLI. The LOGO causes the sequence to restart and login is now in an infinite failure loop. Fix the problem by having the driver, on a pt2pt link, remember NVMe PRLI accept or reject status across logout as long as the link stays "up". When retrying login, if the prior NVMe PRLI was rejected, it will not be sent on the next login.
