Indeed, that did the trick, thanks!  So mesh is functional now with raw mode
patch and a few hacks:

root@archer:~# iw dev
phy#0
        Interface mon0
                ifindex 8
                wdev 0x2
                addr e8:de:27:d6:9c:d0
                type monitor
        Interface wlan0
                ifindex 4
                wdev 0x1
                addr e8:de:27:d6:9c:d0
                type mesh point
                channel 149 (5745 MHz), width: 20 MHz (no HT), center1: 5745 MHz
