This update for open-lldp fixes the following issues:

- Fix for a segementation fault, when agents change their MAC address (bsc#1171284)
- lldapd will now transmit the permanent MAC address (the MAC address of the
underlying physical device) as port id, thus allowing the switch or any
management application to differentiate between those ports. (bsc#1153520)
- Fix for a segmentation fault, when lldapd registers an interface and it
gets shortly removed afterwards. (bsc#1170745)
