I'm looking into it.  The change to iproute2 to support 
(namespace,index) pairs instead of just (index) to identify interfaces 
looks to be invasive.  The rest of it looks like trivial changes.

I've got all these kernel patches tested against my own "namespace aware 
network manager" that I'm writing for a customer with a particular use 
case.  iproute2 wasn't actually in play here.
