Subject: ipv6: Add rt6_get_cookie() function
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=22d2b8ef67c6f31540bf8bf141bba5adca231009;p=pandora-kernel.git

ipv6: Add rt6_get_cookie() function

commit b197df4f0f3782782e9ea8996e91b65ae33e8dd9 upstream.

Instead of doing the rt6->rt6i_node check whenever we need
to get the route's cookie.  Refactor it into rt6_get_cookie().
It is a prep work to handle FLOWI_FLAG_KNOWN_NH and also
percpu rt6_info later.
