Series net: bridge: split IPv4/v6 mc router state and export for batman-adv | expand

Commit Message

Linus Lüssing May 13, 2021, 1:20 p.m. UTC 
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.
