Does RTL8189ETV support 802.11s with OpenWrt

I want to use Openwrt on Orange Pi R1 Plus (with RTL8189ETV chipset) for 802.11s mesh.
Is 802.11s supported on this device?

You have the hardware, check "iw list" and the supported interface modes/ combinations yourself.

Personally, I'd run away screaming with Realtek wireless.

No i don't have one. it looks promising and I plan to buy one, so I'm asking here

Do yourself a favour, pick something with better/ different wireless hardware.
