[dpdk-dev] proposal: raw packet send and receive API for PMD driver

[Lin XU]

I think it is very important to decouple PMD driver with DPDK framework.
   (1) Currently, the rte_mbuf struct is too simple and hard to support complex 
application such as IPSEC, flow control etc. This key struct should be 
extendable to support customer defined management header and hardware 
offloading feature.
   (2) To support more NICs.
So, I thinks it time to add new API for PMD(a no radical way), and developer 
can add initial callback function in PMD for various upper layer protocol 
procedures.
