Subject: [PATCH rdma-next v3 3/3] IB/mlx5: Add page fault handler for DC initiator WQE
Date: Mon, 19 Aug 2019 15:08:15 +0300 [thread overview]
Message-ID: <20190819120815.21225-4-leon@kernel.org> (raw)
In-Reply-To: <20190819120815.21225-1-leon@kernel.org>
From: Michael Guralnik <michaelgur@mellanox.com>
Parsing DC initiator WQEs upon page fault requires skipping an address
vector segment, as in UD WQEs.
