Re: A pure virtual nic

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.

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,
Ben

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

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