Does Omega2 wireless chip support 802.11s mode?

Geo9

I'd like to know if Omega2 supports 802.11s wireless mode for building mesh applications. What wireless driver does it use and what is iw dev command output on OpenWrt?

I have no experience with the WarpCore driver, which is the (proprietary) driver the official Onion FW uses.

But if you use vanilla OpenWrt on the Omega2, the driver is mt76 which definitely does support 802.11s.

What I don’t know, because I have little WiFi knowledge, is wether the MT7866 SoC has the needed HW to allow mt76 to support 802.11s.

But I can provide iw dev on a Omega2 running Wifi with mt76:

# iw dev
phy#0
	Interface wlan0
		ifindex 4
		wdev 0x2
		addr 40:a3:6b:c1:XX:XX
		ssid XXXXXXX
		type AP
		channel 11 (2462 MHz), width: 20 MHz, center1: 2462 MHz
		txpower 13.00 dBm
		multicast TXQ:
			qsz-byt	qsz-pkt	flows	drops	marks	overlmt	hashcol	tx-bytes	tx-packets
			0	0	1009	0	0	0	4	377291		1109

Does not look overly telling to me. But experimenting a bit with what iw has to offer I'd guess iw phy could be more interesting, especially the "mesh point" mode listing

Thank you! Yeah, it looks like it supports 802.11s peering. If it works in practice, that's awesome.
