From 056eed2fb071c11535527fc792bdfb985a9a3e26 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sun, 28 Apr 2019 19:37:14 +0200 Subject: [PATCH] dsa: Add TAG protocol to tag ops In order that we can match the tagging protocol a switch driver request to the tagger, we need to know what protocol the tagger supports. Add this information to the ops structure. Signed-off-by: Andrew Lunn Reviewed-by: Florian Fainelli v2 More tag protocol to end of structure to keep hot members at the beginning.
