💅 ixgbe_get_sfp_init_sequence_offsets — Kernel API Manual

okay so bestie, welcome to the ixgbe_get_sfp_init_sequence_offsets(9) page 🎀 this is a lil function from the Kernel API Manual and it's lowkey the matchmaker between your MAC's EEPROM and your SFP+ module. let's get into it ✨

---

🌸 NAME 🌸

ixgbe_get_sfp_init_sequence_offsets — literally just provides the offset of the PHY init sequence 🫶

---

💖 SYNOPSIS 💖

int ixgbe_get_sfp_init_sequence_offsets (struct ixgbe_hw *hw , u16
*list_offset , u16 *data_offset );

that's the whole signature, no cap. three args, returns an int, and every single character of that is exactly what you type 👑

---

🦋 ARGUMENTS 🦋

• hw — pointer to the hardware structure 💻 like, the whole hardware vibe lives in here
• list_offset — offset to the SFP ID list 🗂️
• data_offset — offset to the SFP data block 📦

three little pointers walk into a function… and honestly that's the bit 😭

---

🌈 DESCRIPTION 🌈

so here's the tea ☕ this function goes and checks the MAC's EEPROM to see if it supports a given SFP+ module type. and if it does? slay. it returns the offsets to the phy init sequence block 🔥

that's it, that's the whole job. no extra side quests, no surprises — just a quick peek in EEPROM and then the coordinates you asked for ✨

🫶 quick vibe check: those are all quoted exactly as the manual has them. don't be out here typo-ing names in a SEE ALSO list, that's not the main character energy we're going for 💅
