net/mlx5e: Eswitch, Use per vport tables for mirroring
When using port mirroring, we forward the traffic to another table and use that table to forward to the mirrored vport. Since the hardware loses the values of reg c, and in particular reg c0, we fail the match on the input vport which previously existed in reg c0. To overcome this situation, we use a set of per vport tables, positioned at the lowest priority, and forward traffic to those tables. Since these tables are per vport, we can avoid matching on reg c0.
