From fcee85f19f39d1b98b2674c2a9e57348fe803252 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Wed, 30 Oct 2019 22:09:19 -0400 Subject: [PATCH] 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 Signed-off-by: David S.
