What exactly do you need?

I believe that you saw the code that produces the event (port active and 
port down events).

The entity that takes care of the machine state of the logical link is 
the openSM (or any other Subnet Manager):
It sends MADs to the IB port between the nodes in the subnet, configures 
the port's properties and
move the logical link to active state.
