📦 version 7.3.1, in nixpkgs unstable

💅 fm10k_iov_supported_xcast_mode_pf 💅

okay bestie, so this is a page straight out of the Kernel API Manual — section 9, kernel-only, very backstage-at-the-driver-conference energy 🎀. The star of the show is fm10k_iov_supported_xcast_mode_pf(9), and honestly? she's a tiny function with one job and she does it. slay.

✨ NAME ✨

fm10k_iov_supported_xcast_mode_pf — literally just here to figure out the best match for an xcast mode 🦋

🌸 SYNOPSIS 🌸

u8 fm10k_iov_supported_xcast_mode_pf (struct fm10k_vf_info *vf_info , u8
mode );

that's it. that's the whole signature. u8 in, u8 out, no cap 💜

🎀 ARGUMENTS 🎀

  • vf_info — the VF info structure, and yes she's the one carrying the capability flags 👑 think of her as the friend who actually remembers everyone's dietary restrictions.
  • mode — the xcast mode you're requesting. your little wish. your ask. 🙈

🔥 DESCRIPTION 🔥

so the way this works is: you hand her a requested mode, and she outputs the mode that most closely matches what you asked for 💖 she's not a yes-man, she's a closest-match girlie.

and if no modes match? then it will request we disable the port 💀 like okay dramatic but fair. no vibe match = no vibe. periodt.

🌈 SEE ALSO 🌈

the whole friend group lives in the kernel file ./drivers/net/ethernet/intel/fm10k/fm10k_pf.c — go say hi to the rest of the family:

ok so real talk: if she can't find a mode that matches, the port gets disabled. that's not a vibe, that's a whole consequence. know before you call her 😭

and that's the page, bestie!! sign-off time 🫶 — this little gem came out of ./drivers/net/ethernet/intel/f... and it's dated October 2026, page header fm10k_iov_s...cast_mode_pf(9) and all. go forth and match those modes 💅✨
