rtnl: add link netns id to interface messages
This patch adds a new attribute (IFLA_LINK_NETNSID) which contains the 'link' netns id when this netns is different from the netns where the interface stands (for example for x-net interfaces like ip tunnels). With this attribute, it's possible to interpret correctly all advertised information (like IFLA_LINK, etc.). Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S. Miller <davem@davemloft.net>
