Public bug reported:

Current code for prefix delegation gets all ports from DB and then for
each port it checks if it has a PD subnet. With this, we get unnecessary
ports(ports without PD subnet) and again we need to check for subnet in
these ports.

We can optimize this by querying the DB by filtering on subnet.
