Example of 6LoWPAN contextual address compression.

Here is an example capture that should demonstrate the automatic context
detection. The router at 2002:db8::ff:fe00:1122 is advertising context
information in its router advertisement messages (first seen in packet #7).
Another device joins the network and attempts to ping three addresses that can
be contextually compressed.

The first ping, seen in packet #45, is is to 2002:db8::ff:fe00:1122, and should
decompress using context-id 0x0 (this is known as the default context, and the
context-id is not included in the packet).

The second ping, seen in packet #55, is to 2002:db8::ff:fe00:1234, and should
decompress using context-id 0x5.

The third ping, seen in packet #63, is to 2002:db8::ff:fe00:1235, and should
decompress using context-id 0xf.
