🌸 ice_get_ieee_or_cee_dcb_cfg(9) — Kernel API Manual 🌸

okay bestie, welcome to the function-page for ice_get_ieee_or_cee_dcb_cfg 💅 this is a Kernel API Manual entry, so it's a little reference card for one single kernel function — no cap, it's short, it's cute, it's giving "index card in a very large filing cabinet" 🗂️

✨ NAME ✨

ice_get_ieee_or_cee_dcb_cfg — and then... a dash. and then nothing 😭

fr fr the description slot is straight-up empty on this one. the dash is just sitting there, alone, no thoughts, head empty 🫠 so like, the name is the name, and if you want the tea you're gonna have to keep scrolling, because it's all down in DESCRIPTION.

🦋 SYNOPSIS 🦋

int ice_get_ieee_or_cee_dcb_cfg (struct ice_port_info *pi , u8 dcbx_mode
);

that's it. that's the whole signature, line break and all 🌈 you hand it a port info pointer and a mode byte, and you get an int back.

🎀 ARGUMENTS 🎀

two things, only two, we love a low-maintenance function 👑

  • pi — the port information structure. this is your port's little info hub, the main character of the story 📋
  • dcbx_mode — the mode of DCBX, and it's u8, and the only two flavours are IEEE or CEE. pick your fighter, bestie ⚔️

🔥 DESCRIPTION 🔥

okay so this is actually the entire description, and I need you to appreciate it:

Get IEEE or CEE mode DCB configuration from the Firmware

yep. that's it. it grabs the DCB config — and it'll do it in IEEE mode or CEE mode depending on what you passed in as dcbx_mode — and the config comes straight from the Firmware 🧚✨ lowkey iconic behaviour honestly, going right to the firmware for the answer instead of guessing.

💀 SEE ALSO 💀

first up, the kernel file this lives in — exact path, screenshot it, don't lose it bestie:

./drivers/net/ethernet/intel/ice/ice_dcb.c

and here's the full extended friend group 🌈 all 41 of them, no skips, no cuts, we don't do that here:

like, look at all those _tlv ones — the ieee crew and the cee crew, both fully represented, we love equal screen time 🫶

that's the whole page, bestie — short but complete 💖 this one's from ./drivers/net/ethernet/intel/ice, dated October 2026, filed under ice_get_ieee_or_cee_dcb_cfg(9). go get that firmware config 👑✨
