Starting from somewhere after R17032 both eth0 and eth1 aren't existing any more.

I have the same problem - dmesg shows only this:

[ 2.370679] ipq806x-gmac-dwmac 37200000.ethernet: IRQ eth_wake_irq not found
[ 2.373813] ipq806x-gmac-dwmac 37200000.ethernet: IRQ eth_lpi not found

Those lines are present in working builds also, but follwed immediately by:
[ 2.381863] ipq806x-gmac-dwmac 37200000.ethernet: PTP uses main clock

And bunch of other messages related coming from ipq806x-gmac-dwmac, but in this case no more messages are coming from ipq806x-gmac-dwmac at all (and no kernel warnings/errors)

In the same time router does correctly detect if the cable is plugged into the eth0/1 ports because the appropriated LED do change state accordingly.

At the time of writing 21.02-SNAPSHOTS work just fine.

After some digging seems that the root of the problem is that mtd partition labeled "default-mac" (cat /proc/mtd) is simply missing in snapshot builds and the drivers try to read MAC address from there. Still looking at the reason why that particular partition is lost because at first glance dts definition in kernel didn't change.
