sis900_check_mode(9)

✨ NAME ✨

okay bestie, welcome to sis900_check_mode(9) from the Kernel API Manual — this function is literally here to check the media mode for sis900. slay. 💅

🎀 SYNOPSIS 🎀

void sis900_check_mode (struct net_device *net_dev , struct mii_phy *mii_phy );

that's the signature exactly, spacing and all, periodt. no edits, no “fixing” it. 🫶

💖 ARGUMENTS 💖

• net_dev — the net device to be checked. yes, the device gets the vibe check. 🦋
• mii_phy — the mii phy. short, iconic, to the point. ✨

🦋 DESCRIPTION 🦋

so the older driver gets the media mode from mii status output register. that's the old lore. now we set our media capability and auto-negotiate to get the upper bound of speed and duplex between two ends. 🔥

and if the types of mii phy is HOME, it doesn't need to auto-negotiate and autong_complete should be set to 1. yes bestie, autong_complete is spelled exactly like that on this page — don't come for me 🙈. also HOME is uppercase, iykyk. 💜
