The new API does not have an equivalent for the below Tx flags:

* ETH_TXQ_FLAGS_NOREFCOUNT
* ETH_TXQ_FLAGS_NOMULTMEMP

The reason is that those flags are not to manage offloads, rather some
guarantee from application on the way it uses mbufs, therefore could not be
present as part of DEV_TX_OFFLOADS_*.
Such flags are useful only for benchmarks, and therefore provide a non-realistic    
performance for DPDK customers using simple benchmarks for evaluation.
Leveraging the work being done in this series to clean up those flags.

I agree that these flags are not offload but benchmark configuration.
They should be deprecated.
