static unsigned int
tcpoptstrip_tg4(struct sk_buff *skb, const struct net_device *in,
		const struct net_device *out, unsigned int hooknum,
		const struct xt_target *target, const void *targinfo)
{
	return tcpoptstrip_mangle_packet(skb, targinfo, ip_hdrlen(skb),
	       sizeof(struct iphdr) + sizeof(struct tcphdr));
}

Example #2
