I'm not sure this is that useful... MAD processing is not such a
super-hot path that we need to keep per-CPU lists of cache-hot buffers
(as is done for sk_buffs), and the kernel slab code should do a pretty
good job of reusing buffers anyway.
(The receive buffer needs to be unmapped before passing to the
consumer anyway so there's not a saving there)
