Subject: [PATCH mlx5-next 08/14] net/mlx5e: Use shared mappings for restoring from metadata
Date: Tue, 3 Aug 2021 16:19:53 -0700 [thread overview]
Message-ID: <20210803231959.26513-9-saeed@kernel.org> (raw)
In-Reply-To: <20210803231959.26513-1-saeed@kernel.org>
From: Roi Dayan <roid@nvidia.com>
FTEs are added with mapped metadata which is saved per eswitch.
When uplink reps are bonded and we are in a single FDB mode,
we could fail to find metadata which was stored on one eswitch mapping
but not the other or with a different id.
To resolve this issue use shared mapping between eswitch ports.
We do not have any conflict using a single mapping, for a type,
between the ports.
