💅 nfp_eth_set_configured(9) — the Kernel API Manual glow-up 🦋

okay so bestie, this is nfp_eth_set_configured from the Kernel API Manual and honestly it's giving "small function, big job" energy. it flips one (1) control bit and the whole PHY either shows up to the party or leaves the group chat. iconic.

✨ NAME ✨

nfp_eth_set_configured — sets that PHY module configured control bit, periodt 🎀

🌸 SYNOPSIS 🌸

int nfp_eth_set_configured (struct nfp_cpp *cpp , unsigned int idx ,
       bool configed );

like literally that's the whole vibe. three args, one int back 💖

🫶 ARGUMENTS 🫶

  • cpp — your NFP CPP handle. the main character of the parameter list ngl 🦋
  • idx — the NFP chip-wide port index. chip-wide, bestie, not per-something-else, don't come for me 🙈
  • configed — the desired state, i.e. what you actually want it to be ⭐

💜 DESCRIPTION 💜

so what does it do? it sets the ifup/ifdown state on the PHY. that's it. that's the whole description. lowkey elegant, highkey important 🔥

up = plugged in and thriving. down = not. the bit does the talking 💅

🔥 RETURN 🔥

here's the vibe check on the return values:

  • 0 — configuration successful, slay 🎉
  • 1 — no changes were needed, it was already that, so nothing happened (still valid, still ate) 💀
  • -ERRNO — configuration failed 😭 and the errno tells you why
fr fr, do not ignore that negative return. -ERRNO means it did not work. that's not a vibe, that's a bug you gotta go fix 🚨
