Support in 6lowpan for RFC4944 address generation
For the conversion of a 16-bit short address in 6lowpan to an IID, there
are several RFCs that produce different results. RFC 4944 section 6
specifies that the conversion uses the given PAN ID and the 16-bit short
address. RFC 6282, on the other hand, specifies thta the conversion only
uses the 16-bit short address and no longer uses the PAN ID.
The current version of the 6lowpan dissector supports only the newer RFC
6282, but there are protocols out there that assume that the address
conversion still abides to RFC 4944.
In order to support these protocols and following the discussion from
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=8970
this patch introduces a boolean preference in the 6lowpan dissector that
indicates whether or not the older RFC 4944 should be used for address
conversion. By default, it is set to FALSE, thus leaving the behavior of
the dissector unchanged.
Besides the boolean preference, another helper function
lowpan_addr16_with_panid_to_ifcid has been written that implements the
expected behavior from RFC 4944 using the same hint mechanism already in
place in the dissector for the support of RFC 6282.
