Wireblast a 100 Gbps packet generator in Go using AF_XDP

That’s very interesting, thank you for sharing. Looks like it could be a very useful tool for testing high performance networking.

I wonder if something similar could be done using TC BPF instead of AF_XDP? My only reservation about AF XDP is that it requires a special NIC to support it, so it may not be useful for a “regular Joe” user. I wonder if TC BPF would also work since it similarly bypasses the Kernel networking stack, I believe you can put packets directly into the NIC TX queue for transmission

The video demo is pretty neat as well https://www.youtube.com/watch?v=8EmxvaOR5uA

ooh no more DPDK, this will make it a lot easier. I just started working with trex but it's all really complicated. Going to give this a try
