From 03bcfb57c098016e318e2672028f93ec072a2333 Mon Sep 17 00:00:00 2001 From: Joe Carnuccio Date: Wed, 30 Mar 2011 11:46:27 -0700 Subject: [PATCH] [SCSI] qla2xxx: Add test for valid loop id to qla2x00_relogin(). If fabric device has invalid loop id (FC_NO_LOOP_ID) then call qla2x00_find_new_loop_id() to attempt to obtain valid loop id.
