Subject: [PATCH for-next v5 6/6] RDMA/rxe: Convert kernel UD post send to use ah_num
Date: Tue, 5 Oct 2021 20:58:15 -0500 [thread overview]
Message-ID: <20211006015815.28350-7-rpearsonhpe@gmail.com> (raw)
In-Reply-To: <20211006015815.28350-1-rpearsonhpe@gmail.com>
Modify ib_post_send for kernel UD sends to put the AH index into the
WQE instead of the address vector.
