I am looking for a way to put an ethernet device in a sort of
"character device" mode where I can simply read and write to it
without going through the TCP/IP stack. I am trying to test some
network hardware and right now I only care that what comes out of it
is identical to what went in to it. Does anyone have any ideas?
