Subject: [PATCH for-next v9 1/9] RDMA/rxe: Add bind MW fields to rxe_send_wr
Date: Mon, 7 Jun 2021 23:25:44 -0500 [thread overview]
Message-ID: <20210608042552.33275-2-rpearsonhpe@gmail.com> (raw)
In-Reply-To: <20210608042552.33275-1-rpearsonhpe@gmail.com>
Add fields to struct rxe_send_wr in rdma_user_rxe.h to support bind MW
work requests
Signed-off-by: Bob Pearson <rpearsonhpe@gmail.com>

v8:
Dropped the flags field in wr.mw which was no longer needed.
The size of the mw struct broke binary compatibility because
it extended the size of the wr union beyond 40 bytes.
