NVIDIA GPUs are supported by drivers/gpu/drm/nouveau/, and your are encourage to support them just like all the other in-tree GPU drivers. Not sure what support a network protocol would need for a specific GPU. You're probably trying to do something amazingly stupid here instead of relying on proper kernel subsystem use.
