Stanislav Fomichev f3d07b02b2 tools: ynl: ethtool testing tool ... This is what I've been using to see whether the spec makes sense. A small subset of getters (mostly the unprivileged ones) is implemented. Some setters (channels) also work. Setters for messages with bitmasks are not implemented. Initially I was trying to make this tool look 1:1 like real ethtool, but eventually gave up :-) Sample output: $ ./tools/net/ynl/ethtool enp0s31f6 Settings for enp0s31f6: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame use: no Supports auto-negotiation: yes Supported FEC modes: Not reported Speed: Unknown!
