In preparation of moving tag_8021q to core DSA, move all initialization and teardown related to tag_8021q which is currently done by drivers in 2 functions called "register" and "unregister". These will gather more functionality in future patches, which will better justify the chosen naming scheme. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.
