* IB/qib: Remove driver specific members from qib qp typeDennis Dalessandro2016-03-118-89/+145
| | | | | | | | | | | | | | | | | In preparation for moving the queue pair data structure to rdmavt the members of the driver specific queue pairs which are not common need to be pushed off to a private driver structure. This structure will be available in the queue pair once moved to rdmavt as a void pointer. This patch while not adding a lot of value in and of itself is a prerequisite to move the queue pair out of the drivers and into rdmavt. The driver specific, private queue pair data structure should condense as more of the send side code moves to rdmavt.
