函数名称：INET_ECN_set_ce

函数原型：static inline int INET_ECN_set_ce(struct sk_buff *skb)

返回类型：int

参数：

类型参数名称
struct sk_buff *skb
146  当:protocol恒等于cpu_to_be16(Internet Protocol packet )
147  如果skb_network_header(skb)加sizeof(structiphdr)小于等于skb_tail_pointer(skb)则返回:IP_ECN_set_ce(ip_hdr(skb))
150  退出
152  当:protocol恒等于cpu_to_be16(IPv6 over bluebook )
153  如果skb_network_header(skb)加sizeof(structipv6hdr)小于等于skb_tail_pointer(skb)则返回:Note:* IP_ECN_set_ce() has to tweak IPV4 checksum when setting CE,* meaning both changes have no effect on skb->csum if/when CHECKSUM_COMPLETE* In IPv6 case, no checksum compensates the change in IPv6 header,* so we have to update skb->csum.
