It doesn't seem to me like this is batman-adv or batmand related. So I would
most likely better to ask on linux-wireless@vger.kernel.org too
And is IBSS mode really required or would meshpoint with mesh_fwding set 0
also work?
iw phy0 interface add mesh0 type mp
ip link set up dev mesh0
iw dev mesh0 mesh join 11s-bat freq 2412 HT20 mcast-rate 18 beacon-interval 1000
iw dev mesh0 set mesh_param mesh_fwding 0
# please make sure that it is actually 0 with: iw dev mesh0 get mesh_param mesh_fwding
ip link set master bat0 dev mesh0

Kind regards,
