Yes, and at what point does it seem like a good idea to hide the channel

people that don't understand how scanning works, but hiding the truth is
never a good idea. NACK.
I can see what you mean, but I think showing seemingly random
fluctuations in channel assignments is at best distracting. Don't you
agree that most people are more interested in seeing the configuration
state than the transient state of the hardware?
I agree, it's very distracting. And while doing mac80211 software scan
the device is on a channel approximately 30 ms with queues stopped, so
no data is transfered at that time. I don't see any benefit from
reporting this value to user space: "Hey, I'm on channel 5 now but by
the time to you read this I will be on channel 6 already."
If people want to follow how mac80211 changes the frequency during scan,
the proper way is to add debug messages for op_config() calls. I saw
that Johannes was already working on that.
To be honest, I would be perfectly happy with this patch if something
like a scanning "flag" were to be show in the output if that is what is
happening. I don't so much need to see the current channel (when in sta
mode at least) as I need to know that the card is scanning if it is not
currently on the channel the AP is on. I'd be very happy to simply see
it say "scanning" next to the channel or some such when this occurs.
thanks,
Rick Farina
