 I have added the SCM header to the wlccp dissector. This header is present in
 packets of base message type 0x01. You can find the specification in the
 following document, when you search for "The table below shows the fields for
 an SCM Advertisement Reply Message.":

 It seems like the header structure in the document is wrong regarding the "SCM
 Node ID" (MAC address) field. From looking at the hexdumps I found out that the
 node id shows up in the header before the "Instance Age" field. There is also a
 2 byte field between the node id and the instance age, which is always zero. I
 have named this field  wlccp.scm_unknown_short, because I don't know what it is
 for.
 
 Me:
 
 Fix two bugs that came up during testing but were present before the patch,
 both involving wrong length handling triggering dissector assert and malformed
 packet messages.
