Do you know what the actual capabilities of the device are? My guess
is that in practice you can have a more liberal feature check and
support a greater range of protocols. Something like this:

Also, does this patch support TSO or just checksums? It looks like
checksums only but in that case it shouldn't expose
NETIF_F_GSO_UDP_TUNNEL.
