i40e_dcbnl_ieee_getpfc(9)

📦 version 7.3.1, in nixpkgs unstable

💅 i40e_dcbnl_ieee_getpfc — the gimme-my-PFC-config girlie (kernel API manual, section 9, bestie)

okay so bestie, picture this: there's a function in the kernel API manual called i40e_dcbnl_ieee_getpfc, and its whole entire job is reading stuff. not writing, not changing, not being messy — just fetching. lowkey iconic behavior honestly 🎀

✨ NAME ✨

i40e_dcbnl_ieee_getpfc — retrieve local IEEE PFC configuration 🌸

like, it goes and gets the local IEEE PFC configuration for you. that's it. that's the whole vibe. no cap.

🦋 SYNOPSIS 🦋

int i40e_dcbnl_ieee_getpfc (struct net_device *dev , struct ieee_pfc
*pfc );

it returns an int, it takes two pointers, and yes the manual really does wrap that line mid-declaration. we love a chaotic line break 💀

💜 ARGUMENTS 💜

  • dev — the corresponding netdev 👑 like, the network device you're asking about. this is your main character device.
  • pfc — structure to hold the PFC information. it's the little container that catches the answer when the function hands it over 🫶

🌈 DESCRIPTION 🌈

Returns local IEEE PFC configuration 🦋

that's the whole thing, bestie. it returns the local IEEE PFC configuration. no side quests, no plot twists, no "oh btw it also modifies state" — the manual says nothing else, so we say nothing else. reading is the assignment and it ate 🔥

👑 SEE ALSO 👑

the source, first of all:

  • Kernel file ./drivers/net/ethernet/intel/i40e/i40e_dcb_nl.c 📁 (this is where the magic literally lives)

and then the whole entire friend group — like, the entire i40e dcbnl roster showed up to the group chat 💅:

and that's the page, bestie!! ✨ it lives over in ./drivers/net/ethernet/intel/i40e, the date stamp on this one says October 2026, and the manual is the Kernel API Manual — section 9, the fancy function-call section 🎀 so go forth, go get that local IEEE PFC configuration, and remember: reading is a slay 💖
