Hi Guy,
[1] Thanks for the quick response. I went through the examples of
t-shark and some codebase. Looks like it does help in my case.
[2] regarding others, RadioTap library is updated in wireshark and
have more additions in terms of header parsing compared to RadioTap
library standalone
[3] "Note that tcpdump has its own code to parse radiotap headers, and
that code doesn't use the Radiotap library.". Thanks for confirmation.
Thanks
