History
Navdeep Parhar 97b84d344d Make the iSCSI parameter negotiation more flexible. 
Decouple the send and receive limits on the amount of data in a single
iSCSI PDU.  MaxRecvDataSegmentLength is declarative, not negotiated, and
is direction-specific so there is no reason for both ends to limit
themselves to the same min(initiator, target) value in both directions.

Allow iSCSI drivers to report their send, receive, first burst, and max
burst limits explicitly instead of using hardcoded values or trying to
derive all of them from the receive limit (which was the only limit
reported by the drivers prior to this change).

Display the send and receive limits separately in the userspace iSCSI
utilities.
