This callback is used to notify that a P2P Device is requesting group owner=
 negotiation with us=2C but we do not have all the necessary information to=
 start GO Negotiation. This indicates that the local user has not authorize=
d the connection yet by providing a  PIN or PBC button press. This informat=
ion can be provided with a call to p2p_connect().
Therefore I'm expecting a new call to p2p_connect(). But the p2p_connect() =
doesn't contain a callback to any function which performs the p2p_build_go_=
neg_resp().I'm gonna try to show you what I should expect:
DEVICE A-->connect-->wpa_supplicant(A)-->go_neg_request-->wpa_supplicant(B)=
-->go_neg_req_rx()-->DEVICE BOnce DEVICE B receives the notification=2C it =
uses p2p_connect to provide the authorizationDEVICE B-->connect-->wpa_suppl=
icant(B)-->go_neg_response-->wpa_supplicant(A)Once wpa_supplicant(A) receiv=
es the response it sends the confirmation.		wpa_supplicant(A)-->go_neg_conf=
irmation-->wpa_supplicant(B)

Can you know what is the flow (induding the respective function callbacks) =
from the wpa_supplicant layer up to control interface ?

Thanks in advance for your time.Best regards=2CAndrea 		 	   		  =
