e1000_write_nvm_82571(9)

📦 version 7.3.1, in nixpkgs unstable

💅 e1000_write_nvm_82571 — like, the whole Kernel API Manual page, bestie ✨

okay so picture this: it's a Kernel API Manual page (yes that's the manual name, we stan a classic), and today's main character is a function that writes to your EEPROM through the ✨appropriate interface✨. no cap, that's the whole vibe. let's get into it 🎀

🦋 NAME 🦋

e1000_write_nvm_82571 — Write to EEPROM using appropriate interface 💖

🌸 SYNOPSIS 🌸

s32 e1000_write_nvm_82571 (struct e1000_hw *hw , u16 offset , u16 words
, u16 *data );

like, that's the signature, save it to your notes app fr fr 📝

✨ ARGUMENTS ✨

  • hw — pointer to the HW structure 🫶 (the hardware, the icon, the moment)
  • offset — offset within the EEPROM to be written to 📍
  • words — number of words to write 🔢
  • data — 16 bit word(s) to be written to the EEPROM 🍓

💜 DESCRIPTION 💜

So for non-82573 silicon, this bad boy writes data to the EEPROM at offset using the SPI interface. slay. that's it, that's the job 💅

⚠️ ok but listen — if e1000e_update_nvm_checksum is not called after this function, the EEPROM will most likely contain an invalid checksum. 😭 not me warning you twice. seriously, call the checksum thing. don't leave it hanging, that's giving chaos and not the cute kind 💀

🔥 SEE ALSO 🔥

bestie the friend group is huge, buckle up, we're going through the whole roster 👑

like, that's everyone. no one got left out. we don't do that here 🫶✨

and that's the page!! 🌈 one last cute lil sign-off from your girl: this one came straight out of the kernel tree at ./drivers/net/ethernet/intel/e1000e/82571.c (the footer had to truncate it to ./drivers/net/ethernet/intel/e... but you get the full path now, you're welcome 💅), and the page is dated October 2026 — so yes, future-era documentation, main character energy fr fr. mwah, go call that checksum function 👑💖
