<p class="MsoNormal">Here I can see that supplciant is calling NL80211_CMD_DEUTHETICATE to nl80211 driver. In cfg80211, it is accepted only if the interface is P2P_CLI or STA. but in our case it is P2PGO hence it fails. The results in we not sending deauth
before going down as a group owner.<o:p></o:p></p>
<p class="MsoNormal">I could trace the functions and could not find out why it should not call NL80211_CMD_DEUTHETICATE in P2PGO case

<p class="MsoNormal">Am I missing something? Can somebody help me to understand why wpa_supplicant_deauthenticate is called which will bound to fail?<o:p></o:p></p>
