can you point me towards how can I add 2 more ethernet ports to RPI 2 board?
USB nics are not an option
and we need an enclosure for this solution
any help will be appreciated
Since the built-in Ethernet port is connected through USB, I'm not sure why USB is not good for the other two. Is it about wires flopping around?
Is the reason for that because you've tried some and they're completely unreliable, causing repeated crashes of your pi?
