Here, you should have:

  if { [ -z "${cnt1}" ] || [ -z "${cnt2}" ]; } &&
     ! mptcp_lib_expect_all_features; then

Because our CI should fail if the failure is not available [1].

I understand that it means the test will fail if we don't use IPRoute2
with your suggested patch, but that's normal: when applying this series,
we can modify the CI docker image to include this support this new feature.


[1] Because only our CI has SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES=1
