Ipq806x NSS build (Netgear R7800 / TP-Link C2600 / Linksys EA8500)

I downloaded the 22.03.5-NSS Unifi HD build from your repo. But ethernet ports are not working. There is no switch chip in this device. There are two ar8033 phys. What could be the problem? NSS is running on stock firmware. Changing Unifi DTS file as below doesn't work.
