<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal">Can you please let us know how to disable GF capability in wpa_supplciant when starting the autonomous P2PGO?<o:p></o:p></p>
<p class="MsoNormal">I can see that <o:p></o:p></p>
<p class="MsoNormal">In file ieee80211n_supported_ht_capab<o:p></o:p></p>
<p class="MsoNormal">if ((conf & HT_CAP_INFO_GREEN_FIELD) &&<o:p></o:p></p>
<p class="MsoNormal"> !(hw & HT_CAP_INFO_GREEN_FIELD)) {<o:p></o:p></p>
<p class="MsoNormal"> wpa_printf(MSG_ERROR, "Driver does not support configured "<o:p></o:p></p>

<p class="MsoNormal"> return 0;<o:p></o:p></p>
<p class="MsoNormal"> }<o:p></o:p></p>
<p class="MsoNormal">So according to the above snippet, if ht_capab has it set in wpa_supplicant but disabled by the driver, it will fail to start.<o:p></o:p></p>
<p class="MsoNormal">Can you please point out how can we disable the GF from the wpa_supplicant? I could not find any parameter for Green Field in wpa_supplicant.conf or is there some other way to disable specific bits in ht_capabilities_info?<o:p></o:p></p>
