Subject: [PATCH mlx5-next 03/14] RDMA/mlx5: Fill port info based on the relevant eswitch
Date: Tue,  3 Aug 2021 16:19:48 -0700	[thread overview]
Message-ID: <20210803231959.26513-4-saeed@kernel.org> (raw)
In-Reply-To: <20210803231959.26513-1-saeed@kernel.org>

From: Mark Bloch <mbloch@nvidia.com>

In shared FDB a single RDMA device can have representors that are
connected to two different eswitches. Use the right eswitch when
preparing the response to userspace.
