https://ufile.io/3x5so this is image for polish device Netiaspot (https://openwrt.org/toh/vtech/netiaspot), where integration between OpenWRT uci and driver works. /lib/wireless/mtlk.sh can be used.
Integration bases on patched hostapd/wpa_supplicant with small patches to iwinfo, luci and script integration.
Unfortunatelly I don't have the source code for patched hybrid of hostapd/wpa_supplicant supporting Wave300 chip - anyway now only patched hostapd is needed, since device is probably not able to work as repeater.
