On a debug kernel it continues to flake :( https://netdev.bots.linux.dev/flakes.html?br-cnt=80&tn-needle=txtimestamp&min-flip=0

This test is time sensitive. It may fail on virtual machines and for debug builds. Similar to commit c41dfb0dfbec ("selftests/net: ignore timing errors in so_txtime if KSFT_MACHINE_SLOW"), optionally suppress failure for timing errors (only).
