Thanks Harris and other ethereal team members
With your active and prompt support and guidance, I have been able to
get the data path up. (11abg card with prism header) and also been able
to ship all the packets (control + mgmt + data) through NDIS in windows
XP.
1) Is there any way by which I can get the values displayed in column
be written in a csv file (like the airopeek)? It would be a nice feature
to record and tabulate the essence of packet information.
2) Is there any seed code on which I could implement the FSM of the
protocol checker, or guidelines for doing so?
The user requirement was like:
1) Just marks if the packet response (eg. ack) was observed or
not.
2) Check for timing
a. Frame response timeout.
b. Txops violation.
c. Latency (maybe)
3) Check for unexpected behavior in bit positions like sequence
number, Time stamps, capability.
Regards
Ankur

You should probably ask the WinPcap developers about this, as it's
probably some low-level issue with NDIS or WinPcap (perhaps the NDIS
stack can't handle the Prism header, as NDIS and the networking stack
might be expecting Ethernet headers).
Note also that there's no way in NDIS to specify that a networking
device has Prism headers, so there's no way for WinPcap to know that
merely by using information from NDIS - assuming you can even arrange
that Prism headers (or AVS headers, or radiotap headers) be present in
the packet (which might not be the case, as per my parenthetical note in
the previous paragraph), you'd have to modify WinPcap to somehow know
that the driver is supplying them, so it can return the right DLT_
value.
