* qla2xxx: Enable SLER conditionally in target mode.Arun Easi2014-09-251-4/+19
| | | | | | | | | | | Sequence level error recovery (aka FC Tape) is not really required for disk devices. On heavily loaded system, with slow turn around, a bunch of status enquiries using REC puts additional burden to the target, so just turn off SLER by default.
