This looks like the packet allocation can be married somewhat nicely in
since SKBs may be built from pages using build_skb(). There may be some

to hold struct skb_shared_info IIRC.

I left some comments on the patch with the allocator in it.

I'll be waiting until Monday to see if some more feedback comes in
before sending out v4, so I expect v4 early next week, FWIW.
