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:

   # Use cases
   #########################################################################
   # Ping LLA with multiple interfaces
   # TEST: Pre cycle, ping out ns-B - multicast IP                    [FAIL]

  With K-azure Standard_D2pds_v5 (arm64) the 8th failure is:
   #########################################################################
   # Use cases
   #########################################################################
   # TEST: Post cycle ns-A eth1, ping out ns-B - multicast IP         [FAIL]
