net: dsa: tag_8021q: clarify index limitation (fcee85f1) · Commits · 戴 / test

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:
