ice_reg_test(9)

💖 NAME 💖

ice_reg_test — perform a register test on a given net_device ✨

Hiii bestie! Welcome to ice_reg_test(9) from the Kernel API Manual. 🫶

✨ SYNOPSIS ✨

u64 ice_reg_test (struct net_device *netdev );

🎀 ARGUMENTS 🎀

• netdev — network interface device structure. That’s the struct you’re handing over, no cap. 💅

💅 DESCRIPTION 💅

Okay so this function performs one of the self-tests required by ethtool. It returns 0 on success and non-zero on failure. So 0 is the slay; non-zero means it did not pass. 😭
