Hi

I am also facing the similar problem and am thinking of using the TZSP
for the encapsulation on windows.

I would be grateful if you could send me a sample tzsp dump so that I
could use it while I am writing the code for encapsulating the raw
802.11 packets in tazman sniffer protocol.

using the online help, as well as going through the source code
enabled me to have some understanding of the encapsulating protocol,
but it would be really beneficial, if I could have a few packets of
actual dumps instead of the simulated ones.

Thanks and Regards
Ankur
