[stgt] [PATCH] iSCSI: Fix bug in parsing of MaxRecvDataSegmentLength

[Ronnie Sahlberg]

Tomo, List,

Please find a patch that fixes a performance problem with MaxRecvDataSegmentLength in TGTD.
It used to ONLY apply this for DISCOVERY sessions but keep the maximum pdu clamped down at a tiny 8kb for all NORMAL sessions.

While the opposite is obviously what was intended.


This should improve performance for large or sequential i/o since it avoids the train of "many DATA-IN PDUs of just 8kb each" that would otherwise be the case for any >8kb reads from the initiator.

regards
ronnie sahlberg
