From 9764ff8807a2455218e2ec5024e823cc09b01906 Mon Sep 17 00:00:00 2001 From: Andrew Vasquez Date: Fri, 31 Jul 2009 15:09:24 -0700 Subject: [PATCH] [SCSI] qla2xxx: Correctly handle 'global port-unavailable' AEN. Treat a global port-unavailable PORT_UPDATE (8014h) AEN as a loop-down event. For this case, within the FCoE domain, the 'logical' interface has been terminated, but the driver will not receive the classic LOOP_DOWN AEN.
