fib_tests.sh is failing in a VM:
$ fib_tests.sh
Running netdev unregister tests
PASS: unicast route test
PASS: multipath route test
Running netdev down tests
PASS: unicast route test
PASS: multipath route test
Running netdev carrier change tests
PASS: local route carrier test
FAIL: unicast route carrier test
The last test corresponds to fib_carrier_unicast_test which 12 places
that could be failing. Be more verbose in the output so a failure is
easier to track down and separate test setup failures with set -e and
set +e pairs.
With the verbose logging it is easier to see which checks are failing:
$fib_tests.sh
Single path route carrier test
....
Carrier down
IPv4 fibmatch [ OK ]
IPv6 fibmatch [ OK ]
IPv4 linkdown flag set [FAIL]
IPv6 linkdown flag set [FAIL]
Second address added with carrier down
IPv4 fibmatch [ OK ]
IPv6 fibmatch [ OK ]
IPv4 linkdown flag set [FAIL]
IPv6 linkdown flag set [ OK ]
