Hi,
It is an overlay on the tx burst API.
Probably it doesn't hurt to add it but we have to be really cautious
with the API definition to try keeping it stable in the future.

Many sample apps include internal buffering for single-packet-at-a-time
operation. Since this is such a common paradigm, this functionality is
better suited to being implemented in the ethdev API.
The new APIs in the ethdev library are:
* rte_eth_tx_buffer_init - initialize buffer
* rte_eth_tx_buf
