If they attach to the same network - not really. Check if you can increase packet sizes, that will help to reduce IRQ load and improve network bandwidth utilization. > > Does driver exist for such a NIC?

Interfacing RTnet through its RTDM interface is not considered a derivative work. Also check the license of the libs you link against, they should all be LGPL. But if you happen to write a proprietary kernel-hosted application, better ask your lawyer.
