问rte_eth_tx_burst无法发送数据包EN所谓“底层数据包”指的是在“运行”于数据链路层的数据包，简单的说就是“以太网帧”，而我们常用的Socket只能发送“运行”在传输层的TCP、UDP等包，这些传输层数据包已经能满足绝大部分需求，但是有些时候还是需要发送底层数据包的（例如SYN扫描），那么如何发送呢？
5)分配并设置以太网设备的发送队列:rte_eth_tx_queue_setup() 6)启动以太网设备:rte_eth_dev_start() 7)从以太网接口接收数据包:rte_eth_rx_burst() 1、UDP协议 用户层经过网络各层,分别会在数据包前面添加 (UDP)协议首部,用于支持UDP的无连接、高效传输 ...
printf(" - Min RX Buffer Size: %u bytes\n",dev_info.min_rx_bufsize); printf(" - Max RX Packet Length: %u bytes\n",dev_info.max_rx_pktlen); // 可以添加更多输出,比如 feature_flags 等等 } return0; } 总结 rte_eth_dev_info_get是一个非常有用的函数,允许开发者在运行时查询和了解他...

Re: [dpdk-dev] rte_eth_tx_burst improperly freeing mbufs from KNI mbuf pool Sorry, I meant that "the mbufs will not be freed as the threshold for freeing seems to not be based on the pool the mbuf originated from, but based on the pool the PMD is configured to use"...
