Babeld removed diversity routing [0], so we need to adjust ubus
bindings. Further. we need to add a patch that makes local_kind
accessible again: "100-local-make-local_kind-function-accessible.patch"

Changelog:
5 May 2022: babeld-1.12
* Implement v4-via-v6 routing (RFC 9229), which allows a router with
IPv4 addresses only to route IPv4. Thanks to Théophile Bastian.
* Enable extended Netlink acks when available.
Thanks to Toke Høyland-Jørgensen.
* Fix restoring of interface configuration to avoid unbounded memory
consumption. Thanks to andrew-hoff.
* Fix handling of deny filters in the install chain.

30 March 2022: babeld-1.11
* Implemented MAC authentication (RFC 8967). Thanks to Clara Dô,
Weronika Kołodziejak and Antonin Décimo.
* Changed the interface of the add_filter function in order to simplify
integration in OpenWRT. Thanks to Nick Hainke.

You can define filter functions in babeld by:
in if eth0 metric 128
This commit adds the ubus equivalent to dynamically add filter on
runtime:
ubus call babeld add_filter '{"ifname":"eth0", "type":"input",
"metric":128}'

25 April 2021: babeld-1.10
* Removed the disambiguation code: source-specific routing is no longer
supported for IPv4, and for IPv6 only on Linux 3.11 or later.
* Fixed an issue handling of retractions with no next hop, which caused
interoperability problems with BIRD. Thanks to Fabian Bläse.
* If skip-kernel-setup is set, we no longer disable the rp_filter, which
makes babeld work in containers. Thanks to Martin Weinelt.
Remove upstreamed part of ubus patch:
- local: make local_kind function accessible

* babeld: send events via ubus
Send a notification via the ubus bus if we experience any changes in
neighbours, routes or xroutes.
The format looks like this:
{route,xroute,neighbour}.add: Object was added
{route,xroute,neighbour}.change: Object was changed
{route,xroute,neighbour}.flush: Object was flushed
If ubus_bindings is turned off, it will minimally effect performance,
since only an if-statement has to be evaluated.
If no subscriber is available, it will minimally change the performance,
since only an if-statmenet that checks for subscribers has to be
evaluated.
