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.
