Hi,

I'm working on Wlan driver and I will be appreciated if you can help me.
    1) The first question is how works the active scanning in the ieee80211 layer. I have tried to debug this function 
and found that io-pkt sends the first "Probe request" packet and then wait for a something. If io-pkt does not get any "
Probe response" packet, scanning has to be terminated by timeout? But this does not happen.
   2) The second question is, How to switch channels during a scan? Does it controlled by io-pkt and how do I know that 
the current channel is changed?

Thanks for advice,
Anton
