Despite the 'net' target, this looks really like net-next material as
most patches look like large refactor. I see there are a bunch of fixes
in patches 3-8, but quite frankly it's not obvious at all what the
refactors/new features described into the commit messages themself
really fix.

I suggest to move this series to net-next (and thus repost after Jan
2), unless you come-up with some good reasons to keep it in net.

Thanks,

Paolo
