Subject: qla2xxx: Fix for continuous rescan attempts in arbitrated loop topology.
X-Git-Tag: v2.6.39-400.9.0~447
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=3edc63b88495317ed92625c19d16fbd4c08dd5c1;p=users%2Fjedix%2Flinux-maple.git

qla2xxx: Fix for continuous rescan attempts in arbitrated loop topology.

Stale information in the temporary fcport created in
qla2x00_configure_local_loop() causes qla2x00_get_port_database() call
to fail. This reschedules scan, which gets stuck continuously in the
rescheduling-of-scan loop due to the failure.

JIRA Key: V2632FC-221
