SubjectBUG: tools/testing/selftests/net/l2_tos_ttl_inherit.sh hangs when selftest restarted
Hi all,

I was wondering whether I am already obnoxious with three or four bug reports in
two days and you might find it easier to hire an assassin to silence me
than to fix them :)

But the saner approach prevailed and I thought of the advantage of pulling
through with 6.2-rc2 selftests on all my available hardware.

Please find included the lshw output, config and dmesg log.
The kernel is essentially vanilla mainline torvalds tree kernel with
CONFIG_KMEMLEAK=y and MG-LRU enabled (somewhat maybe brave, but I believe unrelated).

Of course, I should have tried to fix these myself, but I am not quite an expert
in namespaces.

BTW, Florian asked for a bash -x output, so I am providing one to save one roundtrip:

Kind regards,
