user space network driver api?
 
Does anyone know of a user space framework that will allow me to set up a nic? I have a windows virtual nic that I need to port to linux, but it has to be user space so that my company's tcp proxies aren't given away to the competition.

I'm not aware of any such developments. The topic of 'user space drivers' had come up again in the past few months and the general concession was: why?

If it's any use to you, maybe have a look at 'user mode linux'. It was touted as a great way to develop drivers because when it hung you simply restarted it.

What's wrong with the Linux virtual NICs ; why do you need to port a WinDuhs one?

By setting up a nic, do you mean just assigning addresses and bringing it up or down? In that case, the appropriate framework is a series of socket ioctls. You can learn more about how these work by studying the source of utilities such as ifconfig or ip.

Perhaps you are talking about a TUN or TAP interface? They have a similar API, which you can read about here.
