“struct rte_ether_hdr” 是一个数据结构,用于表示以太网帧的头部。它是由DPDK(Data Plane Development Kit)网络库定义的,用于高性能网络应用程序开发。 在C语言中,结构体的定义如下: structrte_ether_hdr{ uint8_tdst_addr[ETHER_ADDR_LEN]; uint8_tsrc_addr[ETHER_ADDR_LEN]; uint16_tether_type; }; ...

获取UDP 头部:在你的代码中,struct rte_udp_hdr *udphdr = (struct rte_udp_hdr *)(iphdr + 1);是不正确的,因为iphdr是一个指向 IPv4 头的指针,而加法运算会根据其类型(即struct rte_ipv4_hdr *的大小)来进行,这并不是想要得到 UDP 头的正确方式。
