After some preliminary review this looks pretty good to me in so far as adding the necessary hooks to do what I need to do.  I appreciate your effort on this.

I'm sort of a hands-on type of person so I need to apply this patch to a private git tree and then take it for a test drive (so to speak).  If I have further comments I'll get back to you.

Did you have any plans for modifying any user space tools such as 'ip' to use this interface?
