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 <redacted> --- net/dsa/tag_8021q.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-)
