This is an ABI change notice for DPDK 17.08 in librte_ether about changes in rte_eth_txmode structure.
Currently Tx offloads are enabled by default, and can be disabled using ETH_TXQ_FLAGS_NO* flags. This behaviour is not consistent with the Rx side where the Rx offloads are disabled by default and enabled according to bit field in rte_eth_rxmode structure. The proposal is to disable the Tx offloads by default, and provide a way for the application to enable them in rte_eth_txmode structure. Besides of making the Tx configuration API more consistent for applications, PMDs will be able to provide a better out of the box performance. Finally, as part of the work, the ETH_TXQ_FLAGS_NO* will be superseded as well.
