Alexis,
Sure, I can open a bug soon.

Guy,

Yes, the legacy header has NO magic number, whereas the with 802.11n support 
header, the magic number would exist.
It is a fixed value of 00ffabcd.

I think, we can have it by the usual, i.e. by the existing Analyze-->Decode 
As-->PEEKREMOTE decoding.
This is because, perhaps, with the i/p hex-dump, we can first check for the 
'magic number'.
If magic number exists (being a fixed value of 00ffabcd, we can have it as a 
conditional check), we can go ahead to dissect per the 55-byte header format.
Else, if no magic number, then we can dissect for the 20-byte header.

The main objective of the changes, IMHO, is that, to classify the dissections 
(for both 20 & 55-byte headers) in an informative manner; and the 'magic 
number' can be used to select between the 20 OR 55-byte header dissection.
Can you please clarify the reason, to not go by the typical 'Decode As..' from 
your latest reply.


Thanks and Regards,
Emburey
