Hi,
I have modified Erik Quanstrom's raw socket ethernet driver
for 9vx so that it uses the Linux kernel's "tap" device.
It seems to work just fine. I create the tap device first
using "tunctl" which comes with the Usermode Linux toolkit
but I don't think this is necessary.

ps: I am shadowdaemon on IRC.
