ice_is_serdes_muxed(9)

💅 ice_is_serdes_muxed — a Kernel API Manual moment (yes, from the ice docs, section 9, bestie)

okay so picture this: you're deep in the ice driver, and you just need to know one (1) thing about the hardware. that's this page. it's short, it's sweet, it's giving "small function, big responsibility." 🧚✨

---

🌸 NAME 🌸

ice_is_serdes_muxed — literally just tells you whether the serdes is muxed in hardware. that's the whole vibe check. no cap. 💖

---

🦋 SYNOPSIS 🦋

bool ice_is_serdes_muxed (struct ice_hw *hw );

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW struct. yeah. that's it. hand over your hardware struct and let her do her thing 🫶

---

👑 RETURN 👑

• true when the serdes is muxed 😌
• false when the serdes is not muxed 🙈

no in-between, no "kinda," no "it's complicated." iconic behavior, honestly. 💅

and that's the page!! source situation for the sign-off: this comes out of ./drivers/net/ethernet/intel/ice, dated October 2026, and it's the ice_is_serdes_muxed(9) page obvs. go be muxed or don't, you've got this bestie 🎀🦋⭐
