I have a device where the current channel is shown to user-space,
e.g. the operator. We used that to find out on what channel the
current AP is. Or, when the channel is constantly changing, that
the system is still searching for a matching access-point.
I know that for both things there are other ways to query the
same information, but it's convenient nethertheless.
But one thing for which is no other way is to see the actual
channel-changes due to the search for a new AP. If such a thing
would be important (it isn't for me), maybe a nl80211 broadcast
would be better than, thought.
