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.
