sis900_set_config(9)

💅 sis900_set_config — like, the Kernel API Manual page, bestie

okay so this is sis900_set_config(9) from the Kernel API Manual, and honestly? it's a little icon doing one specific job. let's get into it ✨

---

✨ NAME ✨

sis900_set_config — sets the media type, and it does it via net_device.set_config. that's the whole vibe. 🎀

---

🦋 SYNOPSIS 🦋

int sis900_set_config (struct net_device *dev , struct ifmap *map );

literally that's it. short and slay.

---

🌸 ARGUMENTS 🌸

• dev — the net device whose media type is getting changed. main character energy fr.
• map — the ifmap that ifconfig passed down. it's giving "message from the outside world" 💌

---

💖 DESCRIPTION 💖

so what it does: it sets the media type to 10baseT, 100baseT, or 0 (which means auto) — and it does that via ifconfig. 👑

but here's the tea: we support only port changes. everything else you try to change at runtime? ignored. not even looked at. ignored. 🙈

no cap, if you're trying to sneak in some other runtime config change, this function will not be the one. port changes only, bestie. periodt.
