Subject: [PATCH rdma-next 3/3] RDMA/mlx5: Enable decap and packet reformat on FDB
Date: Thu, 6 Jun 2019 14:06:09 +0300 [thread overview]
Message-ID: <20190606110609.11588-4-leon@kernel.org> (raw)
In-Reply-To: <20190606110609.11588-1-leon@kernel.org>
From: Maor Gottlieb <maorg@mellanox.com>
If FDB flow tables support decap operation, enable it on creation,
This allows to perform decapsulation of tunnelled packets by steering
rules. If FDB flow tables support reformat operation, enable it on
creation as well.
