Create a simple, netns-based topology with double, nested UDP tunnels and
perform TSO transfers on top.
Explicitly enable GSO and/or GRO and check the skb layout consistency with
different configuration allowing (or not) GSO frames to be delivered on
the other end.
The trickest part is account in a robust way the aggregated/unaggregated
packets with double encapsulation: use a classic bpf filter for it.
