Subject: [PATCH v3 6/6] RDMA/rxe: Convert kernel UD post send to use ah_num
Date: Thu, 22 Jul 2021 16:22:45 -0500 [thread overview]
Message-ID: <20210722212244.412157-7-rpearsonhpe@gmail.com> (raw)
In-Reply-To: <20210722212244.412157-1-rpearsonhpe@gmail.com>
Modify ib_post_send for kernel UD sends to put the AH index into the
WQE instead of the address vector.
