I've been trying to implement Mikrotik IE. It is a vendor IE that
carries stuff like radio name. Even though it is Mikrotik specific, UBNT
has a patch for madwifi:
https://github.com/jhairtt/ubnt-hal-0.7.379/blob/master/patches/madwifi-dfs-r3319-20080201/074-mtik-ie.patch

The IE is sent in beacon and assoc/reassoc frames. I think the correct
place for this is mac80211, but I'm not sure how should I expose a
switch to this functionality. Is there something like ioctl, or do I have
to implement a switch in nl80211, then in cfg80211 and then finally in
mac80211?

Any advice is greatly appreciated.
