💅 ksz8_ind_read8(9) — a Kernel API Manual moment

okay so bestie, welcome to ksz8_ind_read8(9), straight out of the Kernel API Manual, and no cap this one is a little baddie of a function 💖 like it's not doing the most, but it's doing exactly what it needs to, and honestly? iconic.

---

✨ NAME ✨

ksz8_ind_read8 — the EEE/ACL/PME indirect register read 🌸

yes girl. three whole switch functionalities in one little read. she's versatile.

---

✨ SYNOPSIS ✨

int ksz8_ind_read8 (struct ksz_device *dev , u8 table , u16 addr , u8 *val );

it's giving "four arguments, zero drama" 🎀

---

✨ ARGUMENTS ✨

• dev — the device structure. your main character struct, the whole vibe check happens through her 🫶
• table — function & table select, register 110. that's her whole personality, ok?
• addr — indirect access control, register 111. the address, the coordinates, the "where we at" 💅
• val — the value read. this is where the answer lands, so like… pay attention to her ✨

---

✨ DESCRIPTION ✨

so what she does, bestie: this function performs an indirect register read for EEE, ACL or PME switch functionalities 🔥 that's the whole job, and she does it flawlessly.

the mechanics? both 8-bit registers 110 and 111 are written at once with ksz_write16, using the serial multiple write functionality. the way that she just… writes two registers in one go 😭 efficiency queen. periodt.

---

✨ RETURN ✨

• 0 on success 🎉
• or an error code on failure 💀

that's it. that's the return section. short, sweet, honest. we respect her for it.

okay this list is long, so buckle up bestie, we're going shopping 🛍️

lowkey a reminder from your girl: this is the read one. ksz8_ind_write8(9) is her sibling and she's linked above, don't mix them up 🙈
