I think it is better to keep as it is in this patch, since mainly it copies from one place to another, but can you update this in new patch in this patchset? > + ol_flags |= (tx_offload & DEV_TX_OFFLOAD_QINQ_INSERT) ? > + PKT_TX_QINQ_PKT : 0; Same here, 'PKT_TX_QINQ_PKT' replaced with 'PKT_TX_QINQ'. > + ol_flags |= (tx_offload & DEV_TX_OFFLOAD_MACSEC_INSERT) ? > + PKT_TX_MACSEC : 0; > + > + return ol_flags; > +} > + > +static inline void > +mbuf_field_set(struct rte_mbuf *mb, uint64_t ol_flags, > + uint16_t vlan, uint16_t vlan_outer) > +{ > + mb->ol_flags &= IND_ATTACHED_MBUF | EXT_ATTACHED_MBUF; I guess above line is to prevent those bits overwritten, but with '|=' assignment below I think they will be preserved already, do we need above line? cc'ed Yongseok. > + mb->ol_flags |= ol_flags; > + mb->l2_len = sizeof(struct ether_hdr); > + mb->l3_len = sizeof(struct ipv4_hdr); > + mb->vlan_tci = vlan; > + mb->vlan_tci_outer = vlan_outer; Setting 'vlan_tci' or 'vlan_tci_outer' makes sense only if 'PKT_TX_VLAN' and 'PKT_TX_QINQ' set, since there is already an check for them above, does it make sense to do these assignment in them, for better performance.
