Subject: [PATCH] be2iscsi: Fix MaxXmitDataLenght of the driver.
|
|
|
3f3ec35 |
|
|
|
3f3ec35 |
Issue :
|
|
|
3f3ec35 |
During login negotiation if the MaxRecvDataSegmenLen given by the
|
|
|
3f3ec35 |
target is 0, then MRDSL default value of 8K should be considered.
|
|
|
3f3ec35 |
Some old targets close the CXN if the PDU received size is greater
|
|
|
3f3ec35 |
than the MaxRecvDataSegmentLen set during negotiation.
|
|
|
3f3ec35 |
|
|
|
3f3ec35 |
Fix :
|
|
|
3f3ec35 |
When target is not sending MaxRecvDataSegmentLen in the negotiated
|
|
|
3f3ec35 |
params the value is 0. be2iscsi was setting max_xmit_dlength to 64k
|
|
|
3f3ec35 |
in this case. This fix sets the MaxRecvDataSegmentLen=8k if during
|
|
|
3f3ec35 |
negotiation the MaxRecvDataSegmentLen=0
