Subject: [PATCH mlx5-next v1 05/12] net/mlx5: Report a CQ error event only when a handler was set
Date: Tue, 18 Jun 2019 20:15:33 +0300
Message-ID: <20190618171540.11729-6-leon@kernel.org> (raw)
In-Reply-To: <20190618171540.11729-1-leon@kernel.org>

From: Yishai Hadas <yishaih@mellanox.com>

Report a CQ error event only when a handler was set.

This enables mlx5_ib to not set a handler upon CQ creation and use some
other mechanism to get this event as of other events by the
mlx5_eq_notifier_register API.
