ixgbe_write_eitr(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ixgbe_write_eitr — the ixgbe_write_eitr(9) glow-up 💖

okay so bestie, welcome to the Kernel API Manual page for ixgbe_write_eitr(9) — yes that's the whole title, we're not retyping the header line, that's so not the vibe 🌸

✨ NAME ✨

ixgbe_write_eitr — literally writes the EITR register, but in a hardware-specific way 🎀

🦋 SYNOPSIS 🦋

void ixgbe_write_eitr (struct ixgbe_q_vector *q_vector );

💜 ARGUMENTS 💜

  • q_vector — the struct that's holding all your interrupt and ring info. it's giving "everything bagel" of queue data 🥯

🔥 DESCRIPTION 🔥

so this function is the one that gets called by ethtool, and also by the driver itself, whenever it needs to update EITR registers at runtime. and here's the slay part: all the hardware-specific quirks and differences? handled right here. no cap, this is the one doing the messy work so nobody else has to 💅

like, every chip has its own little opinions about how EITR should be written, and this function is the friend who knows all of them and translates. main character energy, honestly 👑

🌈 SEE ALSO 🌈

the kernel file where all this lives:

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

and the whole extended friend group (iykyk, it's a lot, but we're listing every single one because we don't do half-finished over here 💖):

and that's the whole page, bestie — no flags, no exit statuses, no environment variables hiding in here, just vibes and one very responsible register write 💀

okay bye, this was ixgbe_write_eitr(9) from the Kernel API Manual crew, coming at you out of the kernel source tree at ./drivers/net/ethernet/intel/i... (you know the one 🧚), dated October 2026. mwah 💋 🫶
