Hi,

Jiri Pirko called the batman-adv configuration interface a while back "a
huge mistake" [1] and suggested genl as alternative. The first
reimplementation [2] (based on the team/devlink design) was rejected. This
second implementation is now using a nl80211-like design. The objects
which can now be modified/queried are:

* mesh/soft-interface (BATADV_CMD_GET_MESH/BATADV_CMD_SET_MESH)
* slave/hard-interface (BATADV_CMD_GET_HARDIF/BATADV_CMD_SET_HARDIF)
* vlan (BATADV_CMD_GET_VLAN/BATADV_CMD_SET_VLAN)

Such a set messages automatically triggers a *_SET_* "reply" via the config
multicast group. The same behavior was also added to the sysfs interface.

I would like to ask the other developers to check whether their configuration
values are represented correctly. And please also check whether the current
implementation might collide with some other features which you might have
in your pipeline.

v3:
* correctly assign kernel-doc for BATADV_GW_MODE_CLIENT
* fix validation check for gw.sel_class
* fix setting of BATADV_ATTR_ORIG_INTERVAL
* Cc the (most likely) responsible developers for each setting to more
  directly ask them for feedback
v2:
* rewrite everything in a more nl80211-like message/attribute format.

Kind regards,
        Sven
