From: Jeremy Spewock <jspew...@iol.unh.edu> This series ports over the functionality of the stats_checks test suite from old DTS, but I left it as an RFC just because the verification is different than other test suites that we have written. Mainly because verifying the accuracy of the port statistics while accounting for noise on the wire is not the most straight-forward task. The way I decided to differentiate noise from valid packets in this suite was I used the MAC addresses of the packets and the software packet types that are provided in the verbose output of testpmd.
Another idea for how to do this that I tried was using packet checksums. I wanted originally to send packets with bad checksums and assume that noise on the wire would either have a valid checksum or no checksum at all, but this unfortunately only works for the RX side of verbose output as the TX side does not reflect the same checksum information.
