With CASA CMTS you can mirror DOCSIS traffic from and to a certain MAC address.
There are some Management Packets in the capture, that do not have the
necessary flags fctype and fcparam set.
With this patch we try to dissect DOCSIS packets as management packets and if
this fails, we dissect them as normal ethernet packets.
