💅 ixgbe_setup_fw_link(9) — Setup firmware-controlled PHYs

okay so bestie, welcome to the glow-up era of the Kernel API Manual. this page is all about ixgbe_setup_fw_link(9), and honestly? it's giving "small function, big responsibilities" energy. it does exactly one thing and it does it with its whole chest: setup firmware-controlled PHYs. no cap. 🎀

---

✨ NAME ✨

ixgbe_setup_fw_link — the one where we set up the firmware-controlled PHYs 🧚

like, that's it, that's the whole name section, she's concise and she knows it.

---

🦋 SYNOPSIS 🦋

int ixgbe_setup_fw_link (struct ixgbe_hw *hw );

read it, learn it, love it. returns an int, takes your struct ixgbe_hw *hw, periodt. 💅

---

🌸 ARGUMENTS 🌸

• hw — pointer to hardware structure. that's your hardware bestie, the main character of this whole operation 👑

one argument. one. she's lowkey low-maintenance and we respect that fr fr.

🌈 SEE ALSO 🌈

okay this is the part where the page absolutely pops off, because the cross-reference list is long and honestly iconic. it starts with the kernel file she lives in:

• Kernel file ./drivers/net/ethernet/intel/ixgbe/ixgbe_x550.c

like… that's the whole contact list, bestie. sixty functions and one kernel file, and they all said "yes queen" to being in this section. iykyk. 🫶

no secrets, no hidden options, no weird caveats on this one — just a hardware pointer in, an int out, and a lot of friends in the SEE ALSO. ngl, a rare chill page.

---

and that's the whole vibe check, bestie — this page came from ./drivers/net/ethernet/intel/i... (yep, that's the source/version line, don't @ me) and it's dated October 2026. go forth, set up those firmware-controlled PHYs, and slay 💜✨
