Subject: [PATCH v2 net-next 07/16] net: dsa: tag_ar8331: use generic flow dissector procedure

The switch inside these Atheros chips seems to place the DSA tag before
the Ethernet destination MAC address, so it can use the generic flow
dissector procedure which accounts for a header displacement equal with
the tag length.
