ipv6 address comparison

Hi,

My module uses ipv6_addr_cmp() from <linux/ipv6.h>.

<linux/ipv6.h>
static inline int ipv6_addr_cmp(const struct in6_addr *a1, const struct in6_addr *a2)

{
	return memcmp(a1, a2, sizeof(struct in6_addr));
}

I've included <linux/ipv6.h>. But when i try to build the module i get following error:

net/netfilter/xt_ipaddr.c:81: error: implicit declaration of function ???ipv6_addr_cmp???

Although before the call to ipv6_addr_cmp, i have a casting to struct ipv6hdr *iph. So the definitions from ipv6.h should be available to my module.

cheers.
aft

In my 3.2.0 source tree here the definition is in include/net/ipv6.h, not in include/linux/ipv6.h
