i40e_dcb_need_reconfig(9)

📦 version 7.3.1, in nixpkgs unstable

💖 i40e_dcb_need_reconfig(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for i40e_dcb_need_reconfig — yes the whole manual name is literally right there in the title, iykyk 💅. This is one of those tiny little helper functions in the i40e driver that does exactly one thing and does it iconically. It's giving "small function, big responsibilities." Let's get into it 🫶

✨ NAME ✨

i40e_dcb_need_reconfig — check if DCB needs reconfig 🔍

Like, that's the whole job. It checks. That's it. Slay.

🦋 SYNOPSIS 🦋

bool i40e_dcb_need_reconfig (struct i40e_pf *pf , struct
i40e_dcbx_config *old_cfg , struct i40e_dcbx_config *new_cfg );

Three args, one bool coming back at you. No cap, that's the entire vibe 😌

🎀 ARGUMENTS 🎀

  • pf — board private structure. this is the main-character struct of the whole PF, the one holding all the private state for your board 🏠
  • old_cfg — current DCB config. the "before" pic 📸
  • new_cfg — new DCB config. the "after" pic, the glow-up, the rebrand ✨

🌈 SEE ALSO 🌈

so the kernel file this lives in is:

./drivers/net/ethernet/intel/i40e/i40e_main.c

and then, bestie, there is a list. like a whole list. it's giving "the driver has a lot of functions and I mean a LOT." here we go, every single one, no skipping, periodt 💀

bestie that was a LOT of cross-references and I did not skip a single one 💀 every name is exactly as it appears, fr fr. go read them if you want, they're all in ./drivers/net/ethernet/intel/i40e/i40e_main.c-adjacent land 🧚

and that's the whole page!! 🎀 this came out of the kernel docs for ./drivers/net/ethernet/intel/i40e, dated October 2026, and this manual entry is literally called i40e_dcb_need_reconfig(9) in case the title at the top wasn't obvious enough 💖 mwah, go check your DCB configs, ily 🫶✨
