Subject: [PATCH v2 net-next 13/16] net: dsa: tag_ocelot: use the generic flow dissector procedure

Ocelot switches put their DSA tag before the Ethernet header, so they
shift the other headers and need to call the generic flow dissector
procedure. Do this now, once we've made the injection and the extraction
header use the same length prefixes.
