  [Bluetooth] Handling pending connect attempts after inquiry
  [Bluetooth] Attach low-level connections to the Bluetooth bus
  [IPV6] IP6TUNNEL: Add missing nf_reset() on input path.
  [IPV6] IP6TUNNEL: Delete all tunnel device when unloading module.
  [IPV6] ROUTE: Do not enable router reachability probing in router mode.
  [IPV6] ROUTE: Prefer reachable nexthop only if the caller requests.
  [IPV6] ROUTE: Try to use router which is not known unreachable.
