How to do raw Ethernet under Win32?

How does one do raw Ethernet under Win32? Ultimately, I want
to do it in a Python program, but if somebody can point me to a
clue on how to do it from C, I could probably figure out the
rest.

It looks like I can _almost_ do what I want with the python
wrapper around the windows pcap lib.

Where's PyLibpCap for Windows available?

Here's where I got it from:

I'd take a whack at finishing it, but I don't have a Windows C compiler..

I want to:

1) Send an arbitrary Ethernet packet. [Well, not completely
arbitrary, the source MAC will be "right", but the protocol
number is a proprietary (not IP) one, and the packet isn't
anything standard.

2) Receive any incoming packets with a specified protocl
number -- same proto number as in 1) above.

I've got a program that works under Linux, and I'd like to be
able to port it to Win32...

the new winsock2.h supports more socket types:
/*
* Types
*/
#define SOCK_STREAM 1 /* stream socket */
#define SOCK_DGRAM 2 /* datagram socket */
#define SOCK_RAW 3 /* raw-protocol interface */
#define SOCK_RDM 4 /* reliably-delivered message */
#define SOCK_SEQPACKET 5 /* sequenced packet stream */

so you have only to define 3 as type in the socket() call

The guy you got this from used MINGW, the free GNU compiler for Windows
to do the original port:

I've never done any SWIG stuff before, but it looks like all I
have to do is add some stuff to the .i file to export the
pcap_sendpacket() function.
