Detailed Description

Stores a FIB entry mapping host hwaddr to switch port number.

This class stores an entry for a Forwarding Information Base (FIB) and stores a single mapping between a host hardware address used for ethernet based communication and the physical port on the datapath element pointing towards this station. An entry is a soft-state entity running a timer of length 60 seconds. Once expired, a notification method is called in cfibentry's environment to indicate that is entry has become stale. For timer support, cfibentry derives from class rofl::ciosrv.
