[SRU][Focal][PATCH 0/1] fix rtnetlink.sh for older iproute2 (LP#1896448)

[Kleber Sacilotto de Souza]

BugLink: https://bugs.launchpad.net/bugs/1896448

[ Impact ]
When running the net/rtnetlink.sh selftest from v5.4 on older Ubuntu releases
(e.g. Bionic 18.04), some of the iproute2 CLI options are not available causing
the testcase to fail.

[ Fix ]
SAUCE patch to detect whether some options not present on older iproute2
versions are available, skipping or adapting the tests.

[ Test ]
Run net/rtnetlink.sh on 5.4 kernels with both Focal and Bionic userspace. The
test should complete without introducing regressions on Focal and without
breaking on Bionic.

[ Where problems could occur ]
If the checks for the available interfaces are not done correctly, we could end
up having a smaller coverage on Focal or the tests would still break in Bionic.
