* This callback function is used to request a P2P scan or search
|
|
|
|
* operation to be completed. Type type argument specifies which type
|
|
|
|
* of scan is to be done. @P2P_SCAN_SOCIAL indicates that only the
|
|
|
|
* social channels (1, 6, 11) should be scanned. @P2P_SCAN_FULL
|
|
|
|
* indicates that all channels are to be scanned. @P2P_SCAN_SPECIFIC
|
|
|
|
* request a scan of a single channel specified by freq.
|
|
|
|
* @P2P_SCAN_SOCIAL_PLUS_ONE request scan of all the social channels
|
|
|
|
* plus one extra channel specified by freq.
|
|
|
|
*
|
|
|
|
* The full scan is used for the initial scan to find group owners from
|
|
|
|
* all. The other types are used during search phase scan of the social
|
|
|
|
* channels (with potential variation if the Listen channel of the
|
|
|
|
* target peer is known or if other channels are scanned in steps).
|
|
|
|
*
|
|

|
* The scan results are returned after this call by calling
|
|
|
|
* p2p_scan_res_handler() for each scan result that has a P2P IE and
|
|
|
|
* then calling p2p_scan_res_handled() to indicate that all scan
