Jakub Kicinski 5ef7fdf52c selftests: net: packetdrill: xfail all problems on slow machines ...

We keep seeing flakes on packetdrill on debug kernels, while
non-debug kernels are stable, not a single flake in 200 runs.
Time to give up, debug kernels appear to suffer from 10msec
latency spikes and any timing-sensitive test is bound to flake.
