There is an internal function in ethdev which do translation from the Tx offloads to the txqflags. Checkout ``rte_eth_convert_txq_offloads``.
This is specifically to support PMDs which still use the old offloads API. 

So in fact application needs only to specify the Tx offloads on the tx_conf and those will be converted to txqflags. The PMD see no difference.
