Hello,
I was wondering if someone would be able to point me to where I can find
information on how to use the new ethertap device in the 2.1 kernel. THe
only documentation I have been able to find was in the ethertap.c file
itself and that did not do me much good.

I would appreciate any help on this.

I am hoping I will be able to write raw IP frames to it and it will
redirect them to the correct interface, through the kernel. It looks like
it may be able to do this, but I have not been able to get any where just
playing with it. See the 2.0.30 kernel did this when you would send AW IP
frames to the LoopBack device through a SOCK_PACKET socket, but the 2.1
kernel no longer does this. I will gladly accept other suggestions on how
to do this too.

Thanks for your help.
