i40e_pre_tx_queue_cfg(9)

📦 version 7.3.1, in nixpkgs unstable

💅 i40e_pre_tx_queue_cfg — pre tx queue configure

okay so bestie, welcome to the Kernel API Manual ✨ you're literally about to read the whole entire page for i40e_pre_tx_queue_cfg(9) and honestly? it's giving "tiny function, big responsibility" 🎀

🌸 SYNOPSIS

void i40e_pre_tx_queue_cfg (struct i40e_hw *hw , u32 queue , bool enable
);

like yeah, it's just one line, but the way that it returns void and takes three args? iconic. no cap 🫶

✨ ARGUMENTS

  • hw — pointer to the HW structure 💖 that's your hardware handle bestie, the main character of the whole struct family
  • queue — target PF queue index 🎯 the specific queue we're talking about, PF meaning physical function, iykyk
  • enable — state change request 🦋 it's a bool, so it's a yes/no vibe — are we turning this thing on or off

🔥 DESCRIPTION

So here's the tea ☕ this function handles the hw requirement to indicate intention to enable or disable the target queue. that's literally it. it's the "hey bestie, I'm about to do a thing" heads-up that the hardware requires before you actually do the thing 😭 like a "not me about to change this queue" pre-announcement. it doesn't do the thing itself — it tells the hw what you're intending to do with the target queue. periodt.

🌈 SEE ALSO

first up, the source file itself, living at:

./drivers/net/ethernet/intel/i40e/i40e_common.c

and then the whole entire friend group 👑 (yes, all of them, don't skip, I would never):

like, that's the entire i40e extended family reunion and I love that for them 🌸

ngl bestie, there's no RETURN VALUE section, no ERRORS, no EXIT STATUS — because it returns void. nothing to hand back. it just does the vibe and leaves 💅

and that's the page!! 🦋 this little slice of the Kernel API Manual for i40e_pre_tx_queue_cfg(9) comes from ./drivers/net/ethernet/intel/i40e, dated October 2026 — so if you're citing it, cite it cute, and remember: pre-tx queue config is the "not me about to" of the i40e world 💖✨🎀
