Title:
7 failures reported in net:fcnal-test.sh on Kinetic
Status in ubuntu-kernel-tests:
New
Bug description:
This is not a regression, the test was skipped in the old days due to
the lack of `nettest` command (bug 2006391)
Unlike bug 2006716 ("5 failures reported in net:fcnal-test.sh on
Jammy") there are 7 common failures reported on Kinetic

Sometimes it will fail with 8 failures, but the 8th failure looks
flaky and can be failing on different test cases:
With K-aws c6g.8xlarge (arm64) and r5.large (amd64) the 8th failure is:
