The following tests are failing on debug kernels:

Extend commit 912d6f669725 ("selftests/net: packetdrill: report benign debug flakes as xfail") to cover them.

Thanks.
I see that we'll still have a few flakes on dbg. Perhaps one total failure a day. From the following.
tcp-close-close-local-close-then-remote-fin-pkt tcp-ecn-ecn-uses-ect0-pkt tcp-eor-no-coalesce-retrans-pkt tcp-slow-start-slow-start-after-win-update-pkt tcp-sack-sack-route-refresh-ip-tos-pkt tcp-ts-recent-reset-tsval-pkt tcp-zerocopy-closed-pkt
We'll take a look after this change whether we can make these more resilient. But likely also allow-list or even xfail for everything in dbg.
