ice_aq_sff_eeprom(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ice_aq_sff_eeprom(9) 💖

okay so welcome to the man page for ice_aq_sff_eeprom, bestie — it lives in section 9 of the Kernel API Manual and it's all about poking at the SFF EEPROM on an Intel ice NIC. pull up a chair 🎀

✨ NAME ✨

ice_aq_sff_eeprom —

and that's it. that's the whole name line. the original literally just gives you the function name, a dash, and then… nothing 😭 no one-line summary, no blurb, no nothing. so we move on, no cap.

🌸 SYNOPSIS 🌸

int ice_aq_sff_eeprom (struct ice_hw *hw , u16 lport , u8 bus_addr , u16
mem_addr , u8 page , u8 set_page , u8 *data , u8 length , bool write ,
struct ice_sq_cd *cd );

that's the whole signature, exactly as written — don't let me catch you "tidying" it up 💅

🦋 ARGUMENTS 🦋

okay so this function takes a lot of arguments and every single one matters, so let's go one by one, no skipping 🙈

  • hw — pointer to the HW struct. yes queen, the hardware struct, the main character of the whole thing 👑
  • lport — bits [7:0] = logical port, bit [8] = logical port valid. so the low bits are the port itself and that top bit is the "hey, this port is actually valid" flag ✨
  • bus_addr — I2C bus address of the eeprom (typically 0xA0, 0=topo default). so 0xA0 is the usual vibe, and 0 means you want the topo default 🫶
  • mem_addr — I2C offset. lower 8 bits for address, 8 upper bits zero padding. so the real address lives down in the low byte and the top byte is just padding, lowkey decorative 💀
  • page — QSFP page. yep, that's the page 🌸
  • set_page — set or ignore the page. your call: actually apply it, or just act like it's not there 🙈
  • data — pointer to data buffer to be read/written to the I2C device. the actual payload, the whole point 🍓
  • length — 1-16 for read, 1 for write. so reads can be up to 16 bytes but writes are one byte only, periodt 💅
  • write — 0 read, 1 for write. the switch between "gimme the tea" and "here's the tea" 🔥
  • cd — pointer to command details structure or NULL. optional detail-holder, NULL is totally fine 💜

💫 DESCRIPTION 💫

Read/Write SFF EEPROM (0x06EE)

that's the entire description in the original, bestie — one line, and the opcode 0x06EE is doing all the heavy lifting. it's giving "minimal effort, maximum mystique" 😭

🌈 SEE ALSO 🌈

alright, so this is the part where the original just dumps the entire neighborhood group chat on you. kernel file: ./drivers/net/ethernet/intel/ice/ice_common.c — and then every friend of the family, in the exact order they appeared, because we do NOT skip anyone in this house 💖

okay that's everyone, no one left out, we are nothing if not thorough 💅✨

heads up bestie: that's a genuinely long list, so if you're hunting for a specific function, just ctrl-f the name and let the terminal do the work 🫶

and that's the whole page!! 🎀 this little cutie comes to you from the kernel source tree at ./drivers/net/ethernet/intel/ice, dated October 2026, wearing the very stylish identifier ice_aq_sff_eeprom(9) — go read the source, it's iconic, periodt 💖🔥
