corundum VS libvopono

The GPU uses this: https://github.com/alexforencich/verilog-pcie . And there is an open-source 100G NIC here, including open source 10G/25G MACs: https://github.com/corundum/corundum

Well, I did build this: https://github.com/corundum/corundum

I would look into 10GbE PCS/MAC packet processors implemented under AXI Stream interfaces for example. There are open source examples https://github.com/corundum/corundum and https://netfpga.org/ .

I built my own 100 Gbps capable NIC, along with driver: https://github.com/corundum/corundum. You're welcome to ask if you have any questions, though it is quite a different animal from a 100 Mbps NIC you might have on a microcontroller.

If you're looking for resources, here's one rather comprehensive example of a high-performance FPGA design with a fully custom DMA engine and driver, that runs on both Xilinx and Intel FPGAs: https://github.com/corundum/corundum

I have no idea, but you're welcome to build the design and look at it yourself: https://github.com/corundum/corundum/tree/master/fpga/mqnic/NetFPGA_SUME/fpga. The barrel shifters are in the DMA engine, both the read DMA and write DMA engines have wide barrel shifters.

Dive right into the slack channel and introduce yourself. There is also a new contributor guide. /u/alexforencich/ is on these reddits and he may be able to chime in and give you more concrete suggestions.

But I wanted to switch to communicating with rtnetlink directly first (instead of shelling out to ip etc.) - and did a little bit of work on that here. This would allow you to write programs that can use vopono as a library - creating network namespaces for functions/closures, e.g. for web scraping, etc.

I made some progress with libvopono but still need to add in the wgquick and Openvpn3 functionality.

I'm also (slowly) working on making vopono a library too, so you could run spawn a network namespace and Wireguard connection to run a specific closure (i.e. reqwest requests, etc.) - https://github.com/jamesmcm/libvopono
