Vladimir said when adding this test:
The bridge driver fares particularly badly [...] mainly because
it does not implement IFF_UNICAST_FLT.
See commit 90b9566aa5cd ("selftests: forwarding: add a test for
local_termination.sh").
We don't want to hide the known gaps, but having a test which
always fails prevents us from catching regressions. Report
the cases we know may fail as XFAIL.
