Mtk_soc_eth watchdog timeout after r11573

I am not using anything fancy, really. My network configuration file is below. Mind you, the error is super rare (once in 33 days of uptime) and as far as I could see (but maybe I simply wasn't using my network when it happened) I didn't experience any issues due to it. So I am not TOO bothered right now.
