                  Hello, 

                   
                  I would to know a which level Wireshark/Winpcap samples the IP packets.
                  I use a mobile phone as a modem (DUN). A flow control permits to adjust the data flow from the PC to the modem.

                  We have a downlink and a uplink data flow.
                  Because of this flow control, we can see that the downlink TCP data are not acknowledge immediately.

                  I would like to know where wireshark samples the data?
                  When the data leave the ipstack or when the data leave the PC?
                  Can I configure wireshark/winpcap to sample the packet a layer 3?
                  (I am affraid it could have some important delay between layer3 -> layer 2 -> layer 1)

                  (stack ip -> PPP -> USB -> modem) 


                  Thanks a lot. 
                  Michel
