okay so bestie, welcome to the Kernel API Manual page for generic_mii_ioctl — literally the main MII ioctl interface. no cap, we're gonna go through the signature, the args, the return vibe, and every SEE ALSO bestie. 🫶

generic_mii_ioctl — main MII ioctl interface

✨ SYNOPSIS ✨

int generic_mii_ioctl (struct mii_if_info *mii_if , struct
       mii_ioctl_data *mii_data , int cmd , unsigned int *duplex_chg_out );

it's giving int return, four arguments, zero mystery. 💅

🎀 ARGUMENTS 🎀

• mii_if — the MII interface. main character struct pointer energy, iykyk. 🦋
• mii_data — MII ioctl data structure. the little data bag for the ioctl vibes. ✨
• cmd — MII ioctl command. the command itself, periodt. 👑
• duplex_chg_out — pointer to duplex_changed status if there was no ioctl error. yes bestie, that's the whole condition. 🙈
