There is many reasons, following is not whole. For receiver: 1. NIC 2. __netif_receive_skb(unknown packet type) 3. ip_rcv(abnormal packet, route reason...) 4. tcp/udp (unknown port, receive buff limit..) For Sender: 1. tcp/udp(send buffer limit) 2. ip(route reason....) 3. arp(resolved_discards) 4. qdisc(queue limit) Best Regards Shan Wei
