Subject: [PATCH rdma-next v2 3/6] IB/core: Introduce driver QP type
Date: Tue,  2 Jan 2018 16:19:30 +0200	[thread overview]
Message-ID: <20180102141933.24353-4-leon@kernel.org> (raw)
In-Reply-To: <20180102141933.24353-1-leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>

From: Moni Shoua <monis-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

Vendors can implement type of QPs that are not described in the
InfiniBand specification. To still be able to use the IB/core layer
services (e.g. user object management) without tainting this layer with
driver proprietary logic, a new QP type is added - IB_QPT_DRIVER. This
will be a general QP type that the core layer doesn't know about its true nature.
When a command like create_qp() is passed to a hardware driver the extra
data that is required is taken from the driver channel.
Downstream patches from this series will use that QP type in the mlx5
driver.
