igb_shift_out_eec_bits(9)

💅 igb_shift_out_eec_bits(9) 💅

okay so bestie, welcome to the Kernel API Manual, section 9, and today's main character is igb_shift_out_eec_bits — the little function that pushes bits out to your EEPROM one at a time. yes, one. at. a. time. it's giving patient queen energy 👑

---

✨ SYNOPSIS ✨

void igb_shift_out_eec_bits (struct e1000_hw *hw , u16 data , u16 count
);

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

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. your hardware's whole personality lives in here 💖
• data — the data to send to the EEPROM 📨
• count — number of bits to shift out. yes, you gotta tell it how many 🔢

---

🌸 DESCRIPTION 🌸

so here's the vibe: we need to shift count bits out to the EEPROM. so the value sitting in the data parameter gets shifted out to the EEPROM one bit at a time — literally one, then the next, then the next 🦋

and to make that happen? data has to be broken down into bits first. that's the whole job. that's the assignment. she ate 💅

ngl the original NAME line says "Shift data bits our to the EEPROM" — yeah it's a typo in the manpage itself, we're keeping it, it's iconic 😭
