Hi Tim,

What happens when a core API like rte_mbuf gets some changes, and you have to 
update the PMD's to fit?

Do I have to make 10-20 odd random patches to separate PMD maintainers instead 
of one set of patches to the PMD subtree?

To me it doesn't sound very nice for the guys maintaining the core. Given most 
of the changes seem to be mbuf or eal this seems like a scaling issue to me.

But maybe I misunderstood the process.

Matthew.
