Hi,
I'd like to extend the channel list output in ifconfig to include the DFS flags.
These include:
* D: channel is DFS enabeld
* R: radar event has been detected on this channel
* I: interference has been detected on this channel
* C: CAC has completed on this channel (and thus can be used)
This is primarily to aid IBSS/hostap developers who are tinkering with
DFS/radar detection, but will be useful moving forward when users are
configuring ibss/hostap in DFS enabled areas (when DFS is fully
supported, that is.)
Thanks,
Adrian
