Willem de Bruijn 3f12817fe3 selftests: udp gso with corking 
Corked sockets take a different path to construct a udp datagram than
the lockless fast path. Test this alternate path.

Willem de Bruijn e5b2d91c2d selftests: udp gso with connected sockets 
Connected sockets use path mtu instead of device mtu.

Test this path by inserting a route mtu that is lower than the device
mtu. Verify that the path mtu for the connection matches this lower
number, then run the same test as in the connectionless case.
