* selftests: udp gso with corkingWillem de Bruijn2018-04-261-0/+6
| | | | | | | | Corked sockets take a different path to construct a udp datagram than the lockless fast path. Test this alternate path. Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* selftests: udp gso with connected socketsWillem de Bruijn2018-04-261-0/+7
| | | | | | | | | | | 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.
