As the author of the HSR driver, I'd like to answer this question, but unfortunately 
I don't know what x-netns is. Neither Google nor Documentation/ has been particularly
helpful.

Care to elaborate? (Maybe this is a moot point now that the patch has been accepted,
but I'd still like to understand, if you have the time to explain.)

(Pretty much all I know about network namespaces is from this article:
