I updated a RB500r5 with ROS 3.14 mipsle that comes with firmware 2.17
after upgrading the RouterBoard firmaware to this 2.17 version and rebooting,
Mikrotik only reconise ether1
Downgrading to 3.13 doesn’t solve the problem, only downgrading firmware to 2.16 makes Mikrotik recognize all 3 ethernets of his board.
Perhaps somebody can take a look to firmare 2.17 and see if there is a bug with that issue.
