Willem de Bruijn cda261f421 selftests: add txtimestamp kselftest ... Run the transmit timestamp tests as part of kselftests. Add a txtimestamp.sh test script that runs most variants: ipv4/ipv6, tcp/udp/raw/raw_ipproto/pf_packet, data/nodata, setsockopt/cmsg. The script runs tests with netem delays. Refine txtimestamp.c to validate results. Take expected netem delays as input and compare against real timestamps. To run without dependencies, add a listener socket to be able to connect in the case of TCP. Add the timestamping directory to the kselftests Makefile. Build all the binaries. Only run verified txtimestamp.sh. Signed-off-by: Willem de Bruijn <willemb@google.com> Acked-by: Soheil Hassas Yeganeh <soheil@google.com> Signed-off-by: David S.
