IEEE80211_VIF_BEACON_FILTER IEEE80211_VIF_SUPPORTS_CQM_RSSI So, you should configure this in cw1200_add_interface() for new compat-wireless: vif->driver_flags |= IEEE80211_VIF_BEACON_FILTER | IEEE80211_VIF_SUPPORTS_CQM_RSSI; BR Janusz -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
