Subject: [PATCH mlx5-next 2/2] net/mlx5: Set completion EQs as shared resources
Date: Tue, 14 May 2019 14:44:12 +0300 [thread overview]
Message-ID: <20190514114412.30604-3-leon@kernel.org> (raw)
In-Reply-To: <20190514114412.30604-1-leon@kernel.org>
From: Yishai Hadas <yishaih@mellanox.com>
Mark completion EQs as shared resources so that they can be used by CQs
with uid != 0.
