💖 ice_self_test(9) — the Kernel API Manual glow-up 🎀

okay bestie, so this one lives in the Kernel API Manual and it's genuinely iconic: it's the handler that runs a self-test when ethtool comes knocking. lowkey a whole vibe check for your network card 💅

✨ NAME ✨

ice_self_test — the handler function that performs a self-test, courtesy of ethtool 🫶

🌸 SYNOPSIS 🌸

void ice_self_test (struct net_device *netdev , struct ethtool_test
*eth_test , u64 *data );

like, yes, it's void, it returns nothing, it just does the thing 💀

🦋 ARGUMENTS 🦋

  • netdev — the network interface device structure, aka the whole personality of the NIC you're testing 🎀
  • eth_test — the ethtool_test structure, it's giving paperwork energy
  • data — required by ethtool.self_test, no notes, it's mandatory, periodt ✨

👑 DESCRIPTION 👑

so this function gets called after you invoke the ethtool -t devname command — where devname is the name of the network device that ethtool should operate on, iykyk 💫

then it performs a set of self-tests to check that the device is actually working properly. it's literally the NIC's annual physical 🩺✨ no cap, if something's off, this is how you find out.
