[PATCH net-next v2 10/10] flow_dissector: set encapsulation control flags for non-IP

["Asbjørn Sloth Tønnesen" <ast@fiberby.net>]

Make sure to set encapsulated control flags also for non-IP
packets, such that it's possible to allow matching on e.g.
TUNNEL_OAM on a geneve packet carrying a non-IP packet.
