If it is this license agreement from Nvidia 
https://docs.nvidia.com/cuda/eula/index.html

Then it is clearly not open source and I would have to recommend
against allowing this driver in DPDK. 

Corollary: without a open-source GPU driver, I would also recommend
against including the GPU driver subsystem in DPDK.
