Decade and a half ago there was PacketShader, which used usermode networking+GPUs to do packet routing. https://shader.kaist.edu/packetshader/index.html

I wish someone would take up this effort again. It'd be awesome to see VPP or someone target offload to GPUs again. It feels like there's a ton of optimization we could do today based around PCI-P2P, where the network card could DMA direct to the GPU and back out without having to transit main-memory/the CPU at all; lower latency & very efficient.

That said, just dropping down an fpga right on the nic is probably/definitely a smarter move. Seems like a bunch of hyperscaler do this. Unclear how much traction Marvell/Nvidia get from BlueField being on their boxes but it's there. Actually using the fpga is hard of course. Xilinx/AMD have a track record of kicking out some open source projects tothat seem interesting but don't seem to have any follow through, https://github.com/Xilinx/nanotube and https://github.com/Xilinx/open-nic .
