DESCRIPTION
Utility class that provides functions to create, interpret and modify
LLA identifiers. LLA identifiers are a MIP4 specific hardware definition
used by low-latency handovers. They are not commonly used by the MIP4
entities, unless they are to be added or parsed from a MIP4 registration
request/reply. In all internal state and processing the LLADDR definitions
provided by ipmip_lladdr.h are used, which are a superset of the LLA. That is,
a LLA can be converted to a LLADDR without loss of information, but the
reverse is not necessarily true.
These functions are mostly internal and used for specific events defined
by low latency handoffs and proxy mobility registrations.
