[Cake] Testing wanted: Statistics API rework

[Toke Høiland-Jørgensen]

Hey everyone

As you have probably seen, the posting of CAKE to netdev resulted in
feedback saying that versioned structs are a no-go. Well, I've just
pushed a change to both the cake and tc repos that changes the
statistics reporting to used nested netlink attributes.

If someone has time to test it (especially on mips!), that would be
great; I think we still have a few days left of net-next being open, so
if it works for you, I'll resubmit tomorrow...
