net: dsa: tag_8021q: clarify index limitation
Now that there's no restriction from the DSA core side regarding the switch IDs and port numbers, only tag_8021q which is currently reserving 3 bits for the switch ID and 4 bits for the port number, has limitation for these values. Update their descriptions to reflect that. Signed-off-by: Vivien Didelot <vivien.didelot@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
