Hi Yang,

a small glitch I just noticed: you forgot to update the string used by
Wireshark to get Ncap version (as seen in About Wireshark dialog box:). It
reports "Npcap version 0.04 (packet.dll version 1.00), based on WinPcap
version 4.1.3 (packet.dll version 4.1.0.3001), based on libpcap version 1.0
branch 1_0_rel0b (20091008)".

Pascal.
