[openib-general] [PATCH 2/2] libibverbs-1.0: return sq_draining value in query_qp response

[Jack Morgenstein]

Return the sq_draining value back to user space for query_qp instead
of the en_sqd_async notify value.  This last is valid only for
modify_qp. For query_qp (according to the IB Spec V1.2), the
draining status should returned.

Roland,
   Without this patch, sq_draining management can be done only
via the draining event.  Furthermore, the current situation
does not comply with the IB Spec.
Finally, the ABI structure change is only a name change -
no need to increment the ABI version.

Also, please enter this change for libibverbs 1.1 as well.
