It looks to me kernel doesn't use "USO", so TUN_F_UDP_GSO_L4 is a better
name for this
and I guess we should toggle NETIF_F_UDP_GSO_l4 here?
No, we do not, because this indicates only the fact that the guest can
send large UDP packets and have them splitted to UDP segments.
And how about macvtap?We will check how to do that for macvtap. We will send a separate
patch for macvtap or ask for advice.
