ixgbe_setup_tc(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ixgbe_setup_tc(9) — from the Kernel API Manual, bestie 💖

Okay so picture this: you're deep in the ixgbe driver, the Intel 10-gig situation, and you need the network device to actually understand multiple traffic classes. That's this function. It's the glow-up moment where your net_device gets its TC era. ✨

🌸 NAME 🌸

ixgbe_setup_tc — configure net_device for multiple traffic classes

Literally what it says on the tin, no cap. You hand it a device, you tell it how many traffic classes you want, and it handles the configuring. Main character behavior. 👑

🦋 SYNOPSIS 🦋

int ixgbe_setup_tc (struct net_device *dev , u8 tc );

That's the whole vibe. Returns an int, takes two things, we're gonna talk about them right now. 🫶

🎀 ARGUMENTS 🎀

  • dev — the net device you're configuring. Like, the actual thing getting the makeover. 💅
  • tc — number of traffic classes to enable. It's a u8, so keep it cute and keep it in range. It's the count of TCs you're turning on, periodt. 🔥
Heads up bestie: the man page states exactly this and nothing more — dev is the net device to configure, tc is the number of traffic classes to enable. No extra lore, don't let anyone tell you otherwise. 🙈

💜 SEE ALSO 💜

So the source lives here, and you will be reading it:

  • Kernel file ./drivers/net/ethernet/intel/ixgbe/ixgbe_main.c

And here's the whole friend group — every single one of these, no skipping, I'm not doing that to you:

🌈 PCI, regs, VFs & stats besties

🍓 The RX/TX clean-up crew

⚡ Interrupts, events & firmware icons

🧚 TX/RX configuration & RSS girlies

✨ Resources, MTU, open & close

👑 Watchdog & service task squad

🦄 MAC, bridges, PCI driver life cycle

That's the whole page, bestie — every argument, every reference, nothing dropped. 💖

Sign-off time 🎀 the footer credits the source as ./drivers/net/ethernet/intel/i... (yep, it's truncated like that right on the page, iconic honestly) and it's dated October 2026, all under ixgbe_setup_tc(9). Go configure those traffic classes. Slay. 💅✨
