Subject: [PATCH v3 net-next 05/14] 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 <andrew@...n.ch>
Reviewed-by: Florian Fainelli <f.fainelli@...il.com>
v2
More tag protocol to end of structure to keep hot members at the beginning.
