I've go through the standard again and it looks like it is mandatory
for RedBox to send supervisory frames with MAC addresses from
ProxyNodeTable as its payload. Moreover, the RedBox MAC address shall
be also send as the second (i.e. following) payload in this frame.
The current RedBox (from net-next) needs to be extended to support it
- I've started working on this.
