ixgbe_setup...k_sfp_x550em(9)

💖 ixgbe_setup_mac_link_sfp_x550em(9) — the Kernel API Manual, section 9, bestie ✨

okay so picture this: you're deep in the Intel ixgbe driver, section 9 of the Kernel API Manual, and you meet this function. she's giving very niche, very specific, extremely cunty KR-PHY-for-SFP energy and honestly? we're obsessed 🎀

🌸 NAME 🌸

ixgbe_setup_mac_link_sfp_x550em — bestie, this one configures the KR PHY for SFP 💅

---

✨ SYNOPSIS ✨

int ixgbe_setup_mac_link_sfp_x550em (struct ixgbe_hw *hw ,
ixgbe_link_speed speed , bool autoneg_wait_to_complete );

like, that's the whole signature, no cap 🫶

---

🦋 ARGUMENTS 🦋

• hw — pointer to the hardware structure, aka the main character of this whole operation 👑
• speed — the link speed to force. yes, force, she's not asking 🗣️
• autoneg_wait_to_complete — literally unused. not me including it anyway because the ABI said so 💀

---

🌈 DESCRIPTION 🌈

so what does she actually do? she configures the extern PHY and the integrated KR PHY for SFP support, fr fr. two PHYs, one function, zero drama 🧚

⭐ SEE ALSO ⭐

the whole friend group, and yes you're gonna read every single one of them because I said so 💖

Kernel file ./drivers/net/ethernet/intel/ixgbe/ixgbe_x550.c — that's where she lives, iykyk.
