802.11s compatibility with Linux/OpenWRT

[freebsd-wireless at zx81.pw]

Hi,

Looking at the FreeBSD/mesh wiki page ( 
https://wiki.freebsd.org/WiFi/Mesh ) it says:

"Development is occurring at the FreeBSD HEAD branch and an experimental 
support is present on FreeBSD 8.0."
and
"Given that the Linux 802.11s implementation (in wireless-testing) was 
based on an early draft, we can't talk with Linux mesh nodes."

I have a router (Mikrotik RB435G with an AR9220 card with OpenWRT 
installed) and a FreeBSD12 machine with PCIe-based AR9580 card.

With mesh set up on the FreeBSD machine, a scan on the router lists the 
mesh network but can't ever join.
Correspondingly, with mesh set up on the router, a scan on the FreeBSD 
machine doesn't list the router's mesh.

Does anyone have any confirmation of working interaction between FreeBSD 
and Linux/OpenWRT-based nodes?

Thanks
