TNI, VNI... */ uint16_t flags; struct ether_addr outer_mac_src; struct ether_addr outer_mac_dst; union { struct rte_eth_ipv4_flow outer_ipv4; struct rte_eth_ipv6_flow outer_ipv6; }; uint16_t dst_port; uint16_t src_port; struct ether_addr mac_addr; /**< Mac address to match. */ union { struct rte_eth_ipv4_flow ipv4; struct rte_eth_ipv6_flow ipv6; }; }; Note: It have not finalized yet.
