igb_check_for_link_82575(9)

💖 igb_check_for_link_82575 — a little function that checks for link 💖

okay so bestie, this is a page from the Kernel API Manual, and the star of the show is igb_check_for_link_82575(9). yes the name is a mouthful, we love her anyway 🫶

---

✨ NAME ✨

igb_check_for_link_82575 — literally just: check for link 🦋

---

✨ SYNOPSIS ✨

s32 igb_check_for_link_82575 (struct e1000_hw *hw );

that's it. one argument. she's low maintenance 💅

---

✨ ARGUMENTS ✨

• hw — pointer to the HW structure, aka the hardware info blob. she needs it to do her thing, don't leave her hanging 🙈

---

✨ DESCRIPTION ✨

so here's the vibe check 🔥 the function looks at how the link is doing, and which road she takes depends on SGMII:

• if sgmii is enabled, she uses the pcs register to determine link — fancy route, pcs girlie 💅
• otherwise, she uses the generic interface for determining link — the classic, no-frills route 🎀

two paths, one job, zero drama. periodt ✨

ngl bestie, the only real content here is the sgmii-vs-generic branch — everything else is just the extended family tagging along. but we keep the whole guest list, no cap 🎀
