wpa_supplicant will advertise RRM support
(WLAN_EID_RRM_ENABLED_CAPABILITIES) if the driver has certain
capabilities:
if (!((wpa_s->drv_rrm_flags &
WPA_DRIVER_FLAGS_DS_PARAM_SET_IE_IN_PROBES) &&
(wpa_s->drv_rrm_flags & WPA_DRIVER_FLAGS_QUIET)) &&
!(wpa_s->drv_rrm_flags & WPA_DRIVER_FLAGS_SUPPORT_RRM)) {
wpa_printf(MSG_DEBUG,
"RRM: Insufficient RRM support in driver - do not use RRM");
return;
}
That's almost certainly not true for 7260, as far as I remember that
device predates our work to support RRM, and so the firmware wouldn't
have the corresponding capabilities.
