Yes, using loop from bit 0 to bit 63 in patch 2/3 and 3/3 can work right. But I think this enum type is still useful for other application which need= to loop on all possible offloads.=20 I will submit this patch as a standalone one and using loop from bit 0 to b= it 63 in next version of patch set. > Regards > Qi > > + > > /* > > * If new Rx offload capabilities are defined, they also must be > > * mentioned in rte_rx_offload_names in rte_ethdev.c file. > > @@ -981,6 +1002,29 @@ struct rte_eth_conf { > > */ > > #define DEV_TX_OFFLOAD_SECURITY 0x00020000 > > > > +enum rte_eth_tx_offload_type { > > + ETH_TX_OFFLOAD_FIRST_FEATURE =3D 0, > > + ETH_TX_OFFLOAD_VLAN_INSERT =3D ETH_TX_OFFLOAD_FIRST_FEATURE, > > + ETH_TX_OFFLOAD_IPV4_CKSUM, > > + ETH_TX_OFFLOAD_UDP_CKSUM, > > + ETH_TX_OFFLOAD_TCP_CKSUM, > > + ETH_TX_OFFLOAD_SCTP_CKSUM, > > + ETH_TX_OFFLOAD_TCP_TSO, > > + ETH_TX_OFFLOAD_UDP_TSO, > > + ETH_TX_OFFLOAD_OUTER_IPV4_CKSUM, > > + ETH_TX_OFFLOAD_QINQ_INSERT, > > + ETH_TX_OFFLOAD_VXLAN_TNL_TSO, > > + ETH_TX_OFFLOAD_GRE_TNL_TSO, > > + ETH_TX_OFFLOAD_IPIP_TNL_TSO, > > + ETH_TX_OFFLOAD_GENEVE_TNL_TSO, > > + ETH_TX_OFFLOAD_MACSEC_INSERT, > > + ETH_TX_OFFLOAD_MT_LOCKFREE, > > + ETH_TX_OFFLOAD_MULTI_SEGS, > > + ETH_TX_OFFLOAD_MBUF_FAST_FREE, > > + ETH_TX_OFFLOAD_SECURITY, > > + ETH_TX_OFFLOAD_TOTAL_NUM > > +}; > > + > > /* > > * If new Tx offload capabilities are defined, they also must be > > * mentioned in rte_tx_offload_names in rte_ethdev.c file. > > -- > > 2.7.5
