It's interesting to see that you have a lot of RX packets but few
RX interrupts. This can either be due to mis-configuration of
interrupt flags or RX Watchdog.

1. For interrupt flags you should be using LEVEL triggered IRQ.
2. For RX Watchdog you can try disabling it by adding the
following in your platform wrapper driver (which will be
"dwmac-meson8b.c", at probe):
	"plat_data->force_sf_dma_mode = 1;" and
	"plat_data->riwt_off = 1;"

Thanks,
Jose Miguel Abreu
