This patch contains the following: 1. when hba completion status is good, check for iscsi transport errors (underflow/overflow) prior to checking the scsi status 2. New firmware requires that one marker iocb be issued for each task management command. The patch issues marker iocb immediately following a LUN or Target reset.
