Mikrotik RB493G AR8316 switch0/ETH0 cannot be managed
Username: betelgeux1
Origin: https://bugs.openwrt.org/index.php?do=details&task_id=1020
Exists on OpenWRT 14 and 15, LEDE 17 and Trunk
The behaviour is identical to issues reported on RB951G and RB2011 models.

I have been able to work around the issue by cross-connecting the PoE/
WAN
port to switch0 LAN4 and turning off eth0 CPU. This allows me to use all remaining ports. It’s a horrible kludge, I’m only mentioning it as a temporary workaround.
