net: bridge: mcast: add ip4+ip6 mcast router timers to mdb netlink
Now that we have split the multicast router state into two, one for IPv4 and one for IPv6, also add individual timers to the mdb netlink router port dump. Leaving the old timer attribute for backwards compatibility. Signed-off-by: Linus Lüssing <linus.luessing@c0d3.blue> Signed-off-by: David S. Miller <davem@davemloft.net>
