Implementation of the IEEE 802.15.4 dissector ignores the Auxiliary Security
Header of the MHR (see IEEE 802.15.4-2006 specs p.138). I'm guessing this is
related to the fact that the current implementation does not support the
security layer. While I can agree with the fact that the protected fields are
kept encrypted, the absence of the 'clear' Auxiliary Security Header causes
dissecting errors because it is considered as the beginning of the (protected)
payload.
The attached patch, add two things :
1) Support for dissecting the Auxiliary Security Header
2) Add a preference option to force the dissection of the FCS field as being
in the TI CC24xx format
PS: this is my first patch to Wireshark, any kind of feedback is welcome
