> X-Mailer: git-send-email 1.8.3.1
>
> The ethernet Tx adapter abstracts the transmit stage of an
> event driven packet processing application. The transmit
> stage may be implemented with eventdev PMD support or use a
> rte_service function implemented in the adapter. These APIs
> provide a common configuration and control interface and
> an transmit API for the eventdev PMD implementation.
>
> The transmit port is specified using mbuf::port. The transmit
> queue is specified using the rte_event_eth_tx_adapter_txq_set()
> function.

Olivier,
I am planning to take this patch into next-eventdev tree. Could you
please let us know, if you any comments on above "comments" additions to
lib/librte_mbuf/rte_mbuf.h.
If there is any minor one, I can do it on apply or if it major one
Nikhil can send the next version. Let us know.
