mxl86110_mod...extended_reg(9)

🌸 mxl86110_mod...extended_reg(9) — the Kernel API Manual, bestie edition 🌸

okay so picture this: you're deep in the Kernel API Manual for mxl86110_mod...extended_reg(9) and you just need to flip some bits in a PHY's extended register without wrecking the rest of them. That's the whole vibe of this page. Let's go ✨

---

💖 NAME 💖

mxl86110_modify_extended_reg — modify bits of a PHY's extended register. that's it, that's the function, and honestly? she's iconic for it 👑

---

🦋 SYNOPSIS 🦋

int mxl86110_modify_extended_reg (struct phy_device *phydev , u16 regnum
, u16 mask , u16 set );

---

🎀 ARGUMENTS 🎀

• phydev — pointer to the PHY device structure. your main character struct fr fr 🫶
• regnum — register number to write. which register we're messing with 💅
• mask — bit mask of bits to clear. the "not these ones" list 🙈
• set — bit mask of bits to set. the "yes these ones actually" list ✨

---

⭐ NOTE ⭐

lowkey the most important line on this whole page, no cap:

register value = (old register value & ~mask) | set.

that's the math, bestie. clear the mask bits, then OR in the set bits. it's giving surgical precision 🧚

---

🌈 RETURN 🌈

0 or negative error code. so like... zero means slay, negative means something went wrong and you should probably look at it 😭

mwah 💋 — this little number lives in ./drivers/net/phy, dated October 2026, and the header's still calling it mxl86110_mod...extended_reg(9) because we abbreviate when the name is too long to fit. periods, slay, bye 👑
