That's exactly what this patchset does, Tom. The mapping is done in
vxlan_parse_gpe_hdr and vxlan_build_gpe_hdr.
Ethernet is special, though. It needs to be a standalone mode,
otherwise frames encapsulated including an Ethernet header wouldn't be
processed and there would be no way to send such packets - the only
distinction the driver can use is skb->protocol and that won't become
ETH_P_TEB magically.
