Extends the existing udp programs to allow checking for proper
GRO aggregation/GSO size, and run the tests via a shell script, using
a veth pair with XDP program attached to trigger the GRO code path.
rfc v3 -> v1:
- use ip route to attach the xdp helper to the veth
rfc v2 -> rfc v3:
- add missing test program options documentation
- fix sporatic test failures (receiver faster than sender)

Send udp data between a source and sink, optionally with udp gso.
The two processes are expected to be run on separate hosts.
A script is included that runs them together over loopback in a
single namespace for functionality testing.
