Ethertype DSA encodes exactly the same information in the DSA tag as the non-ethertype variety. So refactor out the common parts and reuse them for both protocols. This is ensures tag parsing and generation is always consistent across all mv88e6xxx chips. While we are at it, explicitly deal with all possible CPU codes on receive, making sure to set offload_fwd_mark as appropriate.

Unlike the other tagging protocols, the 802.1Q config option simply

provides helpers for other tagging implementations that might rely on
|
|
VLAN in one way or another. It is not a complete solution.
|
|

Drivers which use these helpers should select this as dependency.
