[for-next,v6,00/12] rdma_rxe: API extensions

Message

V6:
   Fixed two issues raised by Jason and Zhu.

   Undid the replacement of rwlocks by spinlocks in patch 10/12. On further
   reading it turns out rwlocks were the better choice.

   Missing prototype for rxe_invalidate_mr. This was caused by a regression in
   patch 05/12 which had dropped the actual use of the routine as well as the
   prototype. Fixed.

V5:
   This patch series is a collection of API extensions for the rdma_rxe driver.
   With this patch set installed there are no errors in pyverbs run-tests and
   31 tests are skipped down from 56. The remaining skipped test cases include
	   - XRC tests
	   - ODP tests
	   - Parent device tests
	   - Import tests
	   - Device memory
	   - MLX5 specific tests
	   - EFA tests

   It continues from the previous (v4) set which implemented memory windows and
   has had a number of individual patches picked up in for-next.

   This set (v5) includes:
	   Ported to current head of tree
	   Memory windows patches not yet picked up
	   kernel support for the extended user space APIs:
	     - ibv_query_device_ex
	     - ibv_create_cq_ex
	     - ibv_create_qp_ex
	   Fixes for multicast which is not currently working

   This patch set depends on a matching rdma-core user space library patch set.

   In order to run correctly it is necessary to configure by hand the EUI64 link
   local IPV6 address on systems which use a random link local address (like
   Ubuntu).
