💅 i40e_dcb_hw_set_num_tc(9) — the Kernel API Manual glow-up ✨

Okay bestie, so this is a page straight out of the Kernel API Manual, and it's about one tiny little function that lives in the Intel i40e driver. It's giving "small but does something real" energy, and honestly? We respect it. 🫶

🌸 NAME 🌸

i40e_dcb_hw_set_num_tc —

No cap, the original manpage literally leaves the description blank after that dash. Iconic behaviour, honestly. The name is the moment, the moment is the name. 💀

✨ SYNOPSIS ✨

void i40e_dcb_hw_set_num_tc (struct i40e_hw *hw , u8 num_tc );

She returns nothing (void), she takes two things, and she gets it done. Main character energy fr fr. 🎀

🦋 ARGUMENTS 🦋

  • hw — a pointer to the hw struct. Like, the hardware struct. The vibe check for your actual NIC. 👑
  • num_tc — number of traffic classes. A u8, so keep it smol. 🌈

💖 DESCRIPTION 💖

Configure number of traffic classes in HW. That's it, that's the whole plot. You hand her the hw struct and the num_tc you want, and she goes and configures the traffic class count in the hardware itself. Lowkey powerful. Highkey slay. 🔥

🧚 SEE ALSO 🧚

So she's not alone in this, bestie — the whole i40e DCB friend group is here. First off, she lives in this file:

Kernel file ./drivers/net/ethernet/intel/i40e/i40e_dcb.c

And here's the rest of the squad (literally all of them, no gatekeeping 💜):

Like, that's the whole group chat. Screenshot it. 📸

ngl there's no warnings, no exit statuses, no env vars, no bugs section here — this page is short and sweet and that's her brand. Periodt. 💅

And that's the page, bestie! This cutie came to you from ./drivers/net/ethernet/intel/i40e, dated October 2026 — so like, she's from the future and she's still just configuring traffic classes. Obsessed. 🍓✨ Byeee! 🦋
