mdio_set_flag(9)

🎀 NAME 🎀

okay so bestie, welcome to mdio_set_flag(9) from the Kernel API Manual — this one is literally about setting or clearing a flag in an MDIO register, and it’s giving “tiny but important” energy 💅

✨ SYNOPSIS ✨

int mdio_set_flag (const struct mdio_if_info *mdio , int prtad , int devad , u16 addr , int mask , bool sense );

💅 ARGUMENTS 💅

• mdio — the MDIO interface, aka your little doorway into this whole situation 🚪✨
• prtad — the PHY address, no cap
• devad — the MMD address, periodt
• addr — the register address, the exact spot we’re looking at 🎯
• mask — the mask for the flag, and it’s a single bit set — one bit only, bestie, iykyk
• sense — the new value of the flag, like its fresh little vibe check 🦋

🦋 DESCRIPTION 🦋

This debounces changes: it does not write the register if the flag already has the proper value. Like, why touch it if it’s already slaying? 💀✨

Returns 0 on success, and negative on error. That’s it, that’s the whole mood 🫶
