net/mlx5: Lag, set different uplink vport metadata in multiport eswitch mode
In a follow-up commit multiport eswitch mode will use a shared fdb.
In shared fdb there is a single eswitch fdb and traffic could come from any
port. to distinguish between the ports set a different metadata per uplink port.
