[Winpcap-users] Packet reordering

[LeeGilbert]

Hi, I am Gilber Lee.You must rearrange TCP data according to SEQ value in TCP header because TCP stack uses data retransmission technique for ensuring data transfer.WinPcap itself does not support TCP data arrangement because it is not TCP stack library.
