wpa_supplicant: enable support for IBSS RSN (WPA2 in Ad-Hoc mode)
Please add support for IBSS RSN aka WPA2 in Ad-Hoc mode.
Should be as easy as adding CONFIG_IBSS_RSN=y to wpa_supplicant/config
Sidenote: it does seem that this file is out of date compared to upstream https://w1.fi/cgit/hostap/plain/wpa\_supplicant/defconfig, which has some more options with comments at the end, including the requested option.
