I've been working on some software called Etherate that let's you test (or "rate") an Ethernet connection: https://github.com/jwbensley/Etherate https://github.com/jwbensley/Etherate I use it for testing that devices parse frame headers correctly, that L2 VPNs, rate limiting, QoS etc. are all working correctly. I sometimes find bugs in routers and switches when I find that they parse certain headers incorrectly. I have also been working on a multi-threaded version which doesn't provide any header manipulation, it is a pure Ethernet load generator / sinker for testing higher bandwidths: https://github.com/jwbensley/EtherateMT https://github.com/jwbensley/EtherateMT
