Thanks, I found it - device octm was unknowingly commented out. Maybe
as I have no octm in devinfo I left it out, no idea. Now it works.

Back to the original talk - GPIO. I found on Edgerouter Lite pin 11 is
used for reset switch - aka 'Factory Default' button.

Status is
pin 11:	1	F/D<IN>, caps:<IN,OUT>
when not pressed and
pin 11:	0	F/D<IN>, caps:<IN,OUT>
when pressed.

However, I found a problem with ethernet driver. It works only in
gigabit mode - connected to 100baseT switch is correctly negotiated, it
seems, but no traffic flows, either way, probably. What could I do to
diagnose root cause of this problem?
