* add interface scope to exported IPv6 link local addresses * DUID feature works again * If we receive >1 MTU in the RA we use the last one * Expire RA options separately from the RA * Merge multiple RA options together except when a single is needed * Some memory leaks plugged * Don't overwrite invalid memory when DNSSL options begin with a NULL * Ensure we have a large enough buffer for an escaped DNSSL option from RA
