RDMA/rxe: Fixes mr access supported list
A recent patch incorrectly did not include IB_ACCESS_RELAXED_ORDERING in the list of supported access flags for the rxe driver. The driver actually does nothing related to relaxed ordering but it causes no problems to include it as supported but with no effect. This change caused ib_send_bw and friends to not run correctly. The correct approach is for the driver to allow any of the optional access flags and otherwise ignore them. This patch adds IB_ACCESS_OPTIONAL to the list of rxe supported flags. Fixes: 02ed253770fb ("RDMA/rxe: Introduce rxe access supported flags") Link: https://lore.kernel.org/r/20230613171654.19334-1-rpearsonhpe@gmail.com Signed-off-by: Bob Pearson <rpearsonhpe@gmail.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
