Subject: [PATCH rdma-rc 2/3] IB/mlx5: Fix Raw Packet QP event handler assignment
Date: Wed, 23 Aug 2017 08:35:41 +0300	[thread overview]
Message-ID: <20170823053542.17754-3-leon@kernel.org> (raw)
In-Reply-To: <20170823053542.17754-1-leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>

From: Majd Dibbiny <majd-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

In case we have SQ and RQ for Raw Packet QP, the SQ's event handler
wasn't assigned.

Fixing this by assigning event handler for each WQ after creation.
