xfrm_policy.sh in net from ubuntu_kernel_selftests failed with "expected ping to .254 to fail" on Groovy/Hirsute

Oh I mis-read the test output, looks like it's FAIL as it's expected to FAIL,
perhaps this should be modified to PASS, as eventually this has failed and pass with the rule.

Re-open this, with the return value issue (bug 1909647) fixed, this is still failing on Groovy (5.8.0-49.55).

This issue can be found on Hirsute 5.11.0-13 as well.

Another instance of this failure (detected on G/kvm) would be:

All of these issues seems to be related with missing Kconfigs on linux-kvm, for example:

# grep -nrIi vrf config-5.8.0-50-generic
2984:CONFIG_NET_VRF=m
# grep -nrIi vrf config-5.8.0-1026-kvm
1916:# CONFIG_NET_VRF is not set

# grep -nrIi xfrm_interface config-5.8.0-50-generic

# grep -nrIi xfrm_interface config-5.8.0-1026-kvm
