[PATCH v2 net-next 1/2] net: add GSO UDP L4 and GSO fraglists to the list of software-backed types

[Alexander Lobakin]

Commit e20cf8d3f1f7 ("udp: implement GRO for plain UDP sockets.") and
commit 9fd1ff5d2ac7 ("udp: Support UDP fraglist GRO/GSO.") made UDP L4
and fraglisted GRO/GSO fully supported by the software fallback mode.
We can safely add them to NETIF_F_GSO_SOFTWARE to allow logical/virtual
netdevs to forward these types of skbs up to the real drivers.
