fm10k_update_xcast_mode_vf(9)

📦 version 7.3.1, in nixpkgs unstable

🦋 fm10k_update_xcast_mode_vf 💅

okay so this is a page from the Kernel API Manual, bestie — it's all about fm10k_update_xcast_mode_vf, which is one of those little VF helpers living in the fm10k driver. let's get into it ✨

✨ NAME ✨

fm10k_update_xcast_mode_vf — literally just "Request update of multicast mode" 🎀 that's the whole vibe.

🌸 SYNOPSIS 🌸

s32 fm10k_update_xcast_mode_vf (struct fm10k_hw *hw , u16 glort , u8
mode );

like, it hands you back an s32, and it wants three things: a hw, a glort, and a mode. slay, that's it 💅

🫶 ARGUMENTS 🫶

  • hw — pointer to hardware structure. yep, the actual hardware struct, main character energy 🔥
  • glort — unused 🙈 like it's literally sitting there doing nothing, no cap.
  • mode — integer value indicating mode being requested. so it's a number, and that number is telling the world which mode you want ✨

👑 DESCRIPTION 👑

okay so here's what's actually going down — this function will attempt to request a higher mode for the port so that it can enable either multicast, multicast promiscuous, or promiscuous mode of operation. that's the entire plot 🍓

so basically it's the "hey can we level up the port's xcast game" ask, and the three flavors on the menu are multicast, multicast promiscuous, and promiscuous. periodt 💜

🌈 SEE ALSO 🌈

the kernel file in question is ./drivers/net/ethernet/intel/fm10k/fm10k_vf.c — that's where the magic lives, iykyk 🧚

and here's the whole friend group, all of them in (9) section, all of them iconic in their own way:

ngl bestie, glort being marked unused is sending me 😭 but that's canon, don't come for me, I'm just the messenger 💀

kk that's the whole page!! mwah 💖 this one came straight out of ./drivers/net/ethernet/intel/f... and it's dated October 2026, and the manual page name is, of course, fm10k_update_xcast_mode_vf(9) — go forth and request ye a higher multicast mode, you absolute icon 👑✨🎀
