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).
