Hi,

Well the best and cleanest thing would be if the "global" recycler slab/slub 
was fast enough. Historically it seems like every time the link speed increases 
(now to 10g) alloc/kfree pops up on the profiles but that challenge has sofar
been handled by slab/slub folks. Maybe we should consult them first...

Also there was some discussions to have packet objects in slab.

Cheers.
