802.11s on Linux and Openwrt

Hi,
my current setup is a WRT3200ACM with OpenWrt 19.07.2 r10947-65030d81f3 installed and a nanopi neo2 connected over ethernet. The nanopi runs armbian and a "148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter" usb adapter with this config:

interface=wlx000f00732c08
bridge=br0
ssid=XXX
country_code=DE
ieee80211d=1
hw_mode=g
channel=11
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=XXX
wpa_key_mgmt=WPA-PSK
rsn_pairwise=CCMP
wpa_group_rekey=86400
ieee80211n=1
wmm_enabled=1

# controlling enabled
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0

This seems to work so far but I would like to get 802.11s mesh networking up and running. There seems to be quite a lot of documentation for OpenWrt but has one of you set up such a mesh with OpenWrt and plain Linux components? Is there a howto you could recommend?

greetings,
Hosol
