eth0 establishes link on the N2 with released 5.6.18-meson64 (root@builder) but after switching to nightly 5.7.9-meson64 (root@stable) fails to get ethernet link and errors with

[ 76.174115] meson8b-dwmac ff3f0000.ethernet eth0: PHY [0.0:00] driver [RTL8211F Gigabit Ethernet] (irq=25)
[ 76.278174] meson8b-dwmac ff3f0000.ethernet: Failed to reset the dma
[ 76.278892] meson8b-dwmac ff3f0000.ethernet eth0: stmmac_hw_setup: DMA engine initialization failed
[ 76.287895] meson8b-dwmac ff3f0000.ethernet eth0: stmmac_open: Hw setup failed

I've tracked this to a needed delay in the overlay, a patch is available here:

Thanks for an outstanding build!
