Subject: [PATCH net-next 13/15] net/mlx5: E-Switch, Allow offloading fwd dest flow table with vport

From: Roi Dayan <roid@...dia.com>

Before this commit a fwd dest flow table resulted in ignoring vport dests
which is incorrect and is supported.
With this commit the dests can be a mix of flow table and vport dests.
There is still a limitation that there cannot be more than one flow table dest.
