Were you able to traverse GSO packets between network namespace before adding to NETIF_F_GSO_SOFTWARE? It does appear that veth includes NETIF_F_GSO_ENCAP_ALL, which also allows GSO. In either case, it should not be possible for GSO packets to arrive on a veth device, as that can result in queuing the GSO packet to a recipient socket. In this regard veth is like loopback and must exclude GSO support. I'll take a look.
