Looks good, what changed between v1 and v2? Didn't get the cover
letter in case there was one. ;)

Which tree are you targeting? There are usually a lot of changes
in BPF selftests going the usual route via net and net-next tree
as we often require to put test cases along the BPF patches. Given
the merge window now and given one can regard it as a fix, it's
net tree. I'm also ok if Shuah wants to pick it up this window as
test_kmod.sh hasn't been changed in quite a while, so no merge
conflicts expected.

Anyway, for the patch:

Acked-by: Daniel Borkmann <daniel@iogearbox.net>

Thanks!
