[PATCH 3.10 38/54] netfilter: nf_conntrack: fix rt6i_gateway checks for H.323 helper

[Greg Kroah-Hartman]

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Julian Anastasov <ja@xxxxxx>

[ Upstream commit 56e42441ed54b092d6c7411138ce60d049e7c731 ]

Now when rt6_nexthop() can return nexthop address we can use it
for proper nexthop comparison of directly connected destinations.
For more information refer to commit bbb5823cf742a7
("netfilter: nf_conntrack: fix rt_gateway checks for H.323 helper").
