之前说etharp_output远远不是终点,听起来很吓人啊,不过确实的,终点其实是low_level_output,不对,其实是ETH->DMATPDR = 0,但是我们只要看到low_level_output就行了,那里数据包已经全部构建完成了. 简化后就是这样: err_t etharp_output(struct netif *netif, struct pbuf *q, const ip4_addr_t *ipaddr) {...

一下子攻破了两个函数,最后红框处添加以太网头. 以太网头很简单,就是SRC和DST,然后和类型.然后整个帧就OK了.到netif->linkoutput(netif, p),也就是lowlevel_input. 如图,以太网帧. IP帧 UDP帧 一个包,就这么发出去了.后面的00,是补充,这个后话再说了....
