fm10k_dcbnl_setdcbx(9)

💅 fm10k_dcbnl_setdcbx(9) — the one from the Kernel API Manual, bestie

okay so this page lives in the Kernel API Manual (section 9, we stan) and it's all about fm10k_dcbnl_setdcbx — yes the naming is a little chaotic, the NAME line literally says "get" for a set function, and we're just gonna hold that truth and not fight it 🫶

✨ NAME ✨

fm10k_dcbnl_setdcbx — get the DCBX configuration for the device

yes bestie, that's what the manpage says, "get", on a setter. it's giving legacy naming. we don't argue with the docs, we just report them 💀

---

🌸 SYNOPSIS 🌸

u8 fm10k_dcbnl_setdcbx (struct net_device *dev , u8 mode );

so it hands you back a u8, and it wants two things: a struct net_device * and a u8 mode. icons only ✨

---

🦋 ARGUMENTS 🦋

• dev — the netdev interface for the device. your actual network device. the main character, tbh 👑
• mode — the new mode for this device. literally the new mode you're trying to set on it 💅

---

🎀 DESCRIPTION 🎀

okay so the whole vibe here: this function returns error on attempt to enable anything but IEEE DCB for this interface. that's it, that's the function, no cap.

like — if what you're trying to enable is IEEE DCB? slay. anything else? sorry bestie, that's an error, it's not happening 😭

no extra lore, no secret modes, no "well actually it also does…". the manpage says error, so: error. periodt 🔥

that's the page!! short and sweet, unlike some manpages that go on for 40 options (iykyk 💀)

big sign-off energy: this was served up from the source/version line ./drivers/net/ethernet/intel/f..., dated October 2026, and it's the fm10k_dcbnl_setdcbx(9) page — bye bestie, go set some DCBX 🎀💖🦋
