💅 ixgbe_read_eeprom_bit_bang_generic — Kernel API Manual, bestie edition ✨

okay so this is a page straight out of the Kernel API Manual, and the star of the show is ixgbe_read_eeprom_bit_bang_generic. Yes the name is a whole mouthful, no I will not be shortening it, it's iconic and it knows it 🎀

✨ NAME ✨

ixgbe_read_eeprom_bit_bang_generic — Read EEPROM word using bit-bang 🦋

that's it. that's the vibe. it reads a word from the EEPROM and it does it by bit-banging, which lowkey sounds like a dance move but is extremely real and extremely on purpose.

---

🌸 SYNOPSIS 🌸

int ixgbe_read_eeprom_bit_bang_generic (struct ixgbe_hw *hw , u16 offset
, u16 *data );

like… look at that signature. it returns an int, takes three things, and it's giving "small function, big responsibility" energy fr fr 👑

---

🫶 ARGUMENTS 🫶

• hw — pointer to the hardware structure 💖 this is your main character — the actual hardware you're talking to.
• offset — offset within the EEPROM to be read 🌈 literally where in the EEPROM you're looking, bestie.
• data — read 16 bit value from EEPROM ⭐ that's where the 16-bit value you read comes out. it's a u16 *, so it's a pointer, so yes it writes through it. periodt.

---

🔥 DESCRIPTION 🔥

Reads a 16 bit value from EEPROM through the bit-bang method 💅

that's the whole thing. sixteen bits. from EEPROM. via bit-bang. no cap, that's the description, and honestly? it ate. not every function needs a novel written about it.

🫶 quick reminder bestie: this is the Kernel API Manual, so these all live in kernel land — no user-space shenanigans, no man page drama, just driver internals being their iconic selves 💜
