ptype_base和ptype_all理解,netid_receive_skb()函数注解 在数据包接收过程的那篇笔记中可以知道,在数据包的处理函数netif_receive_skb中,会先看ptype_all中是否有注册的协议,如果有,则调用相应的处理函数,然后再到 ptype_base中,找到合适的协议,将skb发送到相关协议的处理函数.比如ip协议(ip_rcv)或者arp(arp...
skb->users += burst and first thing ip_rcv does is skb_share_check. So not exactly representative for normal udp receive, but precise enough to simulate udp receive with taps on eth0 which do skb_clone as well. My main goal was to benchmark ingress qdisc. So here are the numbers: r...
