lock is added to snmpit.in for Openflow listener port assigning. Unlike the small locks in snmpit stack modules, the OF lock is a big lock in snmpit.in because the critical section includes both the getUsedOpenflowListenerPorts and setOpenflowListener functions and if stack/device small locks are used we have to grab multiple small locks one by one with the risk of dead lock.
