Subject: [PATCH AUTOSEL 4.14 03/19] net/mlx5: Take only bit 24-26 of wqe.pftype_wq for page fault type
Date: Tue, 30 Oct 2018 09:28:08 -0400 [thread overview]
Message-ID: <20181030132824.218056-3-sashal@kernel.org> (raw)
In-Reply-To: <20181030132824.218056-1-sashal@kernel.org>
From: Huy Nguyen <huyn@mellanox.com>
[ Upstream commit a48bc513159d4767f9988f0d857b2b0c38a4d614 ]
The HW spec defines only bits 24-26 of pftype_wq as the page fault type,
use the required mask to ensure that.
