Re: [ECOS] dynamic creation of ethernet instances ?

[Philippe Moutarlier <Philippe dot Moutarlier at attbi dot com>]

Good point .. 

I was reading the docs on how to create a driver. But they apply only 
to physical drivers.
  
What should be done in order to create and hook a virtual driver to the stack 
? 

Would I just need to create an instance of struct eth_drv_sc, fill it in with 
the right callbacks and call if_attach ?
