John Fastabend says:

====================

Not sure if folks want to take this through BPF tree or networking tree.
I took a quick look and didn't see any pending fixes so seems no one
has noticed the panic yet. It reproducible and easy to repro.

I put bpf in the title thinking it woudl be great to run through the
BPF selftests given its XDP triggering the panic.

Sorry maintainers resent with CC'ing actual lists. Had a scripting
issue. Also dropped henqqi has they are bouncing.

Thanks!
