Subject: [PATCH AUTOSEL 4.18 07/33] net/mlx5: Take only bit 24-26 of wqe.pftype_wq for page fault type
Date: Tue, 30 Oct 2018 09:26:31 -0400	[thread overview]
Message-ID: <20181030132657.217970-7-sashal@kernel.org> (raw)
In-Reply-To: <20181030132657.217970-1-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.

Fixes: d9aaed838765 ("{net,IB}/mlx5: Refactor page fault handling")
