📦 version 7.3.1, in nixpkgs unstable

💖 nfp_eth_set_fec(9) — the Kernel API Manual glow-up 💖

okay so bestie, welcome to nfp_eth_set_fec from the Kernel API Manual (section 9, iykyk) — this is the little function that sets the PHY forward error correction control mode. that's it, that's the vibe. she's focused, she's iconic, she does one thing. 🎀

✨ NAME ✨

nfp_eth_set_fec — set the PHY forward error correction control mode, no cap. this is literally her whole personality.

🦋 SYNOPSIS 🦋

int nfp_eth_set_fec (struct nfp_cpp *cpp , unsigned int idx , enum
nfp_eth_fec mode );

like, she takes three things and returns an int. simple. elegant. ate. 💅

🌸 ARGUMENTS 🌸

  • cpp — the NFP CPP handle, bestie. your ticket into the whole CPP situation. 🎟️
  • idx — the NFP chip-wide port index. chip-wide, okay? not per-port-something-else, don't come for me. 🔢
  • mode — the desired fec mode, typed as enum nfp_eth_fec. desired being the key word here — she's the dream, not necessarily the reality. ✨

💜 RETURN 💜

  • 0 — configuration successful, we love a win 🎉
  • 1 — no changes were needed, which honestly is also a win, she was already perfect 💅
  • -ERRNO — configuration failed 😭 the negative errno is doing the talking

🔥 SEE ALSO 🔥

the kernel file herself lives at ./drivers/net/ethernet/netronome/nfp/nfpcore/nfp_nsp_eth.c — go read the source, it's giving main character energy 📖

and here's the whole friend group, lowkey obsessed with all of them:

(and yes there's a __nfp_eth_set_fec(9) in there too — the double-underscore sibling, we stan a family reunion 🫶)

ngl bestie, nothing here is dangerous — just remember -ERRNO means it did not slay, and 1 means she didn't even need to try. 🙈
