Subject: [PATCH 2/5] RDMA/rxe: Change AH objects to indexed
Date: Mon, 28 Jun 2021 17:00:41 -0500 [thread overview]
Message-ID: <20210628220043.9851-3-rpearsonhpe@gmail.com> (raw)
In-Reply-To: <20210628220043.9851-1-rpearsonhpe@gmail.com>
Make changes to rxe_param.h and rxe_pool.c to allow indexing of AH
objects. Valid indices are non-zero so older providers can be detected.
