Subject: [PATCH rdma-next 04/10] RDMA/rtrs: Enable Relaxed Ordering
Date: Mon,  5 Apr 2021 08:23:58 +0300
Message-ID: <20210405052404.213889-5-leon@kernel.org> (raw)
In-Reply-To: <20210405052404.213889-1-leon@kernel.org>

From: Avihai Horon <avihaih@nvidia.com>

Enable Relaxed Ordering fro rtrs client and server.

Relaxed Ordering is an optional access flag and as such, it is ignored
by vendors that don't support it.
