Win32 API for raw Ethernet I/O
Although primarily designed to support DOS packet driver applications, components
of SwsVpkt can also be used by Win32 user mode programs to perform raw Ethernet
frame I/O. This is useful to build packet sniffer applications or to send raw IP
frames even under Windows XP service pack 2.
