💖 igc_check_for_copper_link(9) 💖

okay so bestie, welcome to the igc_check_for_copper_link page — it's a kernel API manual situation, and honestly? kind of iconic.

✨ NAME ✨

igc_check_for_copper_link — check for link (Copper) 🩷

---

🦋 SYNOPSIS 🦋

s32 igc_check_for_copper_link (struct igc_hw *hw );

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure, fr fr. that's the whole vibe.

---

🌸 DESCRIPTION 🌸

so the way this works is: it checks to see of the link status of the hardware has changed. yes, "of" — that's literally what the original says, i'm not fixing it, i don't make the rules 💅

and like, if a change in link status has been detected, then we read the PHY registers to get the current speed/duplex if link exists. that's it, that's the whole function, no cap. lowkey elegant ngl.
