wireshark doesn't actually capture the packets on its own. It uses WinPcap to 
capture the packets from the stack.

WinPcap is implemented as an NDIS protocol driver, so it works in parallel with 
other protocols like TCP/IP. Things are a bit more complex when it comes to 
VPNs and dialup adapters.

I hope this answers your questions.

Have a nice day

  Subject: [Wireshark-dev] Newbie question about capture point


  Hello, 

  I was wondering where exactly does wireshark capture eth packets or frames on 
the windows stack( or somwhere on NDIS)?

  Would it be before it reaches the device driver?

  Thank you.
