The idea is to use OFPPS_LIVE bit to propagate link aliveness state towards the controller also when sending port status. The ofport->may_enable flag could be used for this purpose, thus any change in LIVE bit is propagated towards conrtoller in OFPT_PORT_STATUS message. OFPPS_LIVE bit is set only when links is not down not administratively, neither operationally as recommended in OF papers. I added 9 new unit tests to verify link state changes when monitored with cfm, bfd or lacp for OF 1.3, OF 1.4 and OF 1.5. I updated related unit tests according to the changes of ofproto-dpif.
