question: private void processNewPort ( DatapathId sw , OFPort p ) { if ( isLinkDiscoverySuppressed ( sw , p ) ) { return ; } IOFSwitch iofSwitch = switchService . getSwitch ( sw ) ; if ( iofSwitch == null ) { return ; } NodePortTuple npt = new NodePortTuple ( sw , p ) ; discover ( sw , p ) ; addToQuarantineQueue ( npt ) ; }
target:  Process a new port. If link discovery is disabled on the port, then do nothing. If autoportfast feature is enabled and the port is a fast port, then do nothing. Otherwise, send LLDP message. Add the port to quarantine.
