On Ubiquiti module that LOS bit does not work.

I think that on CarlitoxxPro module LOS bit worked. But I cannot test it
right now as I do not have access to testing OLT unit.

Adding Thomas to loop. Can you check if CarlitoxxPro GPON ONT module
supports LOS or other bits at byte offset 110 at address A2?
