#1119 created some conflicts

@cowo78 I can do a review once they are resolved.

Am I right in that this only adds bus.state support for can/interfaces/ixxat/canlib_vcinpl1.py and not for can/interfaces/ixxat/canlib_vcinpl2.py?

Correct. As mentioned in #1119 I would suggest to postpone a refactoring / code deduplication do another PR.

[felixdivo]

I'd like this to get a single other review before merging.
