This test suite needs to be comprehensive that the UAPI works as
designed and fails when it should - cleanly and with an extack message
as to why some config option fails. Tests should cover the datapath -
that it works properly when it should and fails cleanly when it should
not. If addresses are involved in the configuration, then the tests need
to be written for non VRFs, with VRFs and default VRF since addresses
are relative.

Also, in tree test suites are best for the maintenance of this code
going forward.
