From 749af3d54a6d5619088ecadb1010c6ab7766f519 Mon Sep 17 00:00:00 2001 From: Anirban Chakraborty Date: Fri, 14 Nov 2008 13:48:12 -0800 Subject: [PATCH] [SCSI] qla2xxx: Code changes for vport bus reset The following patch changes the handling of bus reset when issued from a vport. In the bus reset code, an extra check is made to make sure that the lip reset is not done before resetting the targets if the bus reset came from a vport.
