💅 igb_get_phy_id(9) — Kernel API Manual 🫶

ok so bestie, welcome to the igb_get_phy_id(9) glow-up page ✨ this one lives in the Kernel API Manual and honestly? it's a little icon. let's get into it.

---

🌸 NAME 🌸

igb_get_phy_id — the girl whose whole job is retrieving the PHY ID and revision 👑

✨ SYNOPSIS ✨

s32 igb_get_phy_id (struct e1000_hw *hw );

that's it. that's the whole entrance. main character energy fr fr 🎀

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure 💖 literally just a pointer, lowkey humble of her, but she's the key to everything here. hand her the hardware struct and she'll do her thing.

💜 DESCRIPTION 💜

kay so what she actually does: she reads the PHY registers 📖👀 and stores the PHY ID — and possibly the PHY revision — into the hardware structure. note the "possibly" bestie, that's not me being vague, that's canon 🙈 the revision is a maybe, the ID is the moment.

so like. registers in → ID (and maybe revision) out → dropped right into hw. no cap, that's the vibe check and she passes 💅✨

🧚 friendly reminder: "possibly" is doing a lot of work in that sentence, so don't go assuming the revision's always coming home with you 🫶
