I'm new to python and generally not very skilled at writing tests, so thanks. The change you did to my regex brings the result in place with IUnixParser, so there could be an test added checking that.

Important note is, that the regex as you changed it, will match invalid VLAN interfaces (they can only have numbers after the dot).

P.S. The MTU PR has the number #39

Thanks @fdellwing - have changed the reference.

so there could be an test added checking that.

That's already added in testss/ip_tests.py :)
