3.19.8-ckt6 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexei Potashnik <alexei@xxxxxxxxxxxxxxx>
commit d20ed91bb60ca54c42e3326251287ec51ed225a1 upstream.
There are multiple reasons for disabling this:
1. It provides no functional benefit. We pretty much only get a few more
sysfs entries for each port, but all that information is already
available from /sys/kernel/debug/target/qla-session-X
2. It already only works in private-loop mode. By disabling we'll be
getting more uniform behavior with fabric mode.
3. It creates complications for the new PLOGI handling mechanism:
scsi_transport_fc port deletion timer could race with new session
from initiator and cause logout after successful login.
