Subject: [PATCH rdma-rc v2 22/48] RDMA/cm: Convert starting PSN to be u32 variable
Date: Thu, 12 Dec 2019 11:38:04 +0200
Message-ID: <20191212093830.316934-23-leon@kernel.org> (raw)
In-Reply-To: <20191212093830.316934-1-leon@kernel.org>

From: Leon Romanovsky <leonro@mellanox.com>

Remove extra conversion between be32<->u32 for starting PSN
by using newly created IBA_GET/IBA_SET macros.
