Okay, I've incorporated most of Guy's suggestions.
Changes from the last patch:
1) New functions are static, and out of the .h file.
2) Instead of decrypting in-place, we create a child tvbuff with the
decrypted data and all that fun stuff.
3) Now the de-weping of fragments should actually work. :)
It does not automagically detect whether or not the FCS is present because
there's no way to know based on the 802.11 headers.
One remaining question is what to do with WEP packets that we can't
decode. Do we treat them as raw data, or pass them down to the llc
dissector?
(Blame the aironet cards that de-wep stuff but leave the WEP bit+IV+ICV
in-place. :)
