selftests: fixes for UDP GRO

2019-03-01T19:24:00Z

The current implementation for UDP GRO tests is racy: the receiver may flush the RX queue while the sending is still transmitting and incorrectly report RX errors, with a wrong number of packet received. Add explicit timeouts to the receiver for both connection activation (first packet received for UDP) and reception completion, so that in the above critical scenario the receiver will wait for the transfer completion.

selftests: add functionals test for UDP GRO

2018-11-08T00:23:05Z

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) Signed-off-by: Paolo Abeni Signed-off-by: David S.
