This patch series implements the xrc transport for the rdma_rxe driver.
It is based on the current for-next branch of rdma-linux.
The first two patches in the series do some cleanup which is helpful
for this effort. The remaining patches implement the xrc functionality.
There is a matching patch set for the user space rxe provider driver.
The communications between these is accomplished without making an
ABI change by taking advantage of the space freed up by a recent
patch called "Remove redundant num_sge fields" which is a reprequisite
for this patch series.

The two patch sets have been tested with the pyverbs regression test
suite with and without each set installed. This series enables 5 of
the 6 xrc test cases in pyverbs. The ODP case does is currently skipped
but should work once the ODP patch series is accepted.
