ixgbe_enable...ispeed_fiber(9)

👑 ixgbe_enable_tx_laser_multispeed_fiber(9) — the one where we turn the laser ON ✨

okay bestie, welcome to the Kernel API Manual 💖 you're reading the page for ixgbe_enable_tx_laser_multispeed_fiber(9) (the header up top truncates it all cute as ixgbe_enable...ispeed_fiber(9), iykyk) — and no cap, this one's a little baddie with main character energy.

---

🌸 NAME 🌸

ixgbe_enable_tx_laser_multispeed_fiber — literally just Enable Tx laser 🔥 that's it, that's the whole vibe.

---

⭐ SYNOPSIS ⭐

void ixgbe_enable_tx_laser_multispeed_fiber (struct ixgbe_hw *hw );

yes she takes exactly one argument, she returns void, she's lowkey iconic 🎀

---

🦋 ARGUMENTS 🦋

• hw — pointer to hardware structure 💅 like, the actual hardware struct, bestie, hand it over

---

💜 DESCRIPTION 💜

so here's the tea 🍵 — the base drivers may require better control over SFP+ module PHY states. highkey a vibe check moment, fr fr.

and that control includes selectively turning on the Tx laser on the PHY, which effectively starts physical link 🔥✨ like, the laser goes on and the link literally begins. that's the whole point. not me being obsessed with a function that flips a laser on 🫶

it's giving "tiny function, enormous responsibility" — the physical link does not start until this girl says so 💀

mwah 💋 that's the page!! sourced from ./drivers/net/ethernet/intel/i... (yes the terminal cut it off, she's mysterious like that 🙈) and dated October 2026, living in the Kernel API Manual, still answering to her full header name ixgbe_enable...ispeed_fiber(9). take care of her, she starts your physical link 🫶✨
