From 646d3857b95e8e310aae7a4594f43d7f3b100a1f Mon Sep 17 00:00:00 2001 From: Brian King Date: Fri, 14 Nov 2008 13:33:53 -0600 Subject: [SCSI] ibmvfc: Handle port login required response The virtual fibre channel stack can return a failure response for a command indicating the port login has been invalidated without sending the client an async event. Add code to handle this response and initiate a PLOGI.
