ixgbe_setup_mac_link_sfp_n(9)

💅 ixgbe_setup_mac_link_sfp_n(9) — from the Kernel API Manual, bestie ✨

Okay so picture this: you're deep in the ixgbe driver, the X550 corner of the kernel, and you need the internal PHY speaking native SFP. That's literally this function's whole job. It lives in ./drivers/net/ethernet/intel/ixgbe/ixgbe_x550.c and it's giving "small function, big responsibility." 🫶

🌸 NAME 🌸

ixgbe_setup_mac_link_sfp_n — sets up the internal PHY for native SFP. That's the entire vibe check, no cap.

---

✨ SYNOPSIS ✨

int ixgbe_setup_mac_link_sfp_n (struct ixgbe_hw *hw , ixgbe_link_speed
speed , bool autoneg_wait_to_complete );

Three params, one int coming back at you. Slay. 💖

---

🎀 ARGUMENTS 🎀

• hw — pointer to the hardware structure. Your whole world of registers and vibes lives in here.
• speed — the link speed. That's it, that's the parameter.
• autoneg_wait_to_complete — unused. 😐 Not "sometimes used," not "used in a special case" — unused. She's just there to keep the signature company, and honestly? Respect.

---

🦋 DESCRIPTION 🦋

Configure the integrated PHY for native SFP support. That's the whole description, and it ate. 💅 It's the native-SFP counterpart in the setup-link family — no drama, no surprises, just internal PHY configuration for native SFP.

Ngl, keep in mind the original says configure and nothing more — so don't go inventing extra behaviour in your head. What you see is what you get, periodt. 👑

And that's the page!! Source path got cut off at ./drivers/net/ethernet/intel/i... (the suspense is real 🙈), dated October 2026, all filed sweetly under ixgbe_setup_mac_link_sfp_n(9). Go configure that native SFP PHY, bestie — you're the main character of the X550 driver now. 💜✨🦋
