Peer sync before sending P2P action frame

[Atul Joshi]

Hi,
When handling P2P-INVITE or P2P-CONNECT for sending a p2p-invitation-req or p2p-go-negotiation-req, the sender needs to ensure that the peer device is in the listen state.
P2P specification suggests to send a Probe request and wait for Probe response to ensure this before sending the above requests..
Is the wpa_supplciant responsible for ensuring that or is it the responsibility of the underlying driver (mac80211/vendor specific) /device to ensure that peer's listen state is ensured before sending the request over the air?
I looked through the supplicant code but could not find a place where it is done.. Have I  missed something?

Thanks
