This is even worse.  We already have two naming conventions in the

To make it clear, in mlx5 this is used only for the offloads/switchdev mode
and not for legacy mode, in the latter mode, a  VF probed to VM doesn't
have host side representation so there's no where to use that.

Or.

which is better for two reasons: (a) it works with multi-PF devices;
(b) naming something representor from switchdev perspective is
pointless, you're not calling the external port netdev a physical port
representor, even though it has the exact same relation to the port as
with VFs (i.e. egressing traffic on the netdev will cause the switch
to send to the given port).
