Can you please let us know how to disable GF capability in wpa_supplciant when starting the autonomous P2PGO?
I can see that
In file ieee80211n_supported_ht_capab
if ((conf & HT_CAP_INFO_GREEN_FIELD) &&
                    !(hw & HT_CAP_INFO_GREEN_FIELD)) {
                                wpa_printf(MSG_ERROR, "Driver does not support configured "
                                                   "HT capability [GF]");
                                return 0;
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.
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?
