Is there a way to generate an ethernet packet, with an unsupported protocol
through a user level program?

I attempted to generate an ethernet packet by opening a socket by calling
socket(AF_UNSPEC, SOCK_RAW, PF_UNSPEC), and it fails with a protocol
unsupported.  Is there a way using standard socket calls to write ethernet
packets?

If not, is there any way to do it?  Any source code as examples?

Thanks

Michael
