I have opened a project in SourceForge, it provides a pure virtual
ethernet adapter. If you are interested to join it, please mail me.
Project Name: pvnet

Is veth or tap (both in vanilla kernel) not enough for you? What are
the differences?

I plan to add some protocols to it. For example, HTTP Proxy packet
analysis. So user-space programs can use an NIC in common way in a
proxy needed environment.

When a program transmits a packet on your virtual NIC, where does the
packet go? When it receives a packet, where did the packet come from?
Thanks,

When a program sends out a packet, at start_xmit function. it will
unpack it and packet again with HTTP proxy headers, then give it to
the actual physical ethernet adapter.
When it receives a packet, unpack it and remove the http proxy
headers, and then put it back to the queue in kernel.

A netfilter module is a much more appropriate way to implement this.
You can even implement this kind of packet mangling in userspace using
nfqueue.
