[RFC,v2,00/19] batman-adv: netlink restructuring, part 2

  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.

Luckily, Jiri Pirko told us that he will have a look at patches. I would
also 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.

v2:
* rewrite everything in a more nl80211-like message/attribute format.

Kind regards,
        Sven
