Hrm. There is a problem with the test. It works with upstream 5.19
kernel, but it fails on some older distribution kernels. Both kernel
and userspace tests fail, because p0 namespace replies only to a first
fragmented ICMP request.
Does it require any specific fix in the kernel to work correctly?
The only relevant recent kernel change I found is:
d9b5ae5c1b24 ("openvswitch: Fix setting ipv6 fields causing hw csum failure")
