Wifi Direct GO Negotiation

[Anand Moon]

Hi All,

I would like to add new question to this thread.

If the AP has the capability to support p2p and wps, how will 
these two devices communicate with the AP. 
Will this AP become P2P group owner (P2P Go) and the other devices P2P Clients ?

I would like to know how to judge if the wireless interface supports P2P
is it with the "Supported interface modes" or "Supported RX frame types" ? 

If the device support following p2p mode then how do we need to configure them. 

Supported interface modes: 
??????? * IBSS
???????  * managed
????????* AP * AP/VLAN 
??????? * monitor 
??????? * mesh point 
??????? * P2P-client 
??????? * P2P-GO 

How do we configure these P2P?modes for interface?
Please share your thoughts.

-Anand Moon

Both devices have their own go intent configuration in wpa_supplicant 
configuration file. D2 sends own go intent value in the GO negotiation 
response. The device with the highest GO intent will become GO.
