From 221726d41a6c351fd8ea7d4b11ab13085f7a8647 Mon Sep 17 00:00:00 2001 From: Seokmann Ju Date: Thu, 3 Apr 2008 13:13:31 -0700 Subject: [PATCH] [SCSI] qla2xxx: Correct vport configuration-change handling. Upon having configuration changes on vports only, the driver handles SCR regardless physical port state and, in turn, it results mailbox error as below: Mar 20 11:24:20 dl585 kernel: qla2x00_mailbox_command(9): **** FAILED. mbx0=4005, mbx1=1, mbx2=8100, cmd=70 **** With the changes, driver checks physical port loop_state and make sure the port is ready to take commands.
