e1000e_write_itr(9)

📦 version 7.3.1, in nixpkgs unstable

💅 e1000e_write_itr — like, the whole manual, bestie

Okay so bestie, we're doing a kernel API page today — this one lives under the e1000e_write_itr(9) manual entry, and it's genuinely such a little function but she's important. Sit down, grab a snack, let's go 🍓

✨ NAME ✨

e1000e_write_itr — no cap, this is the one that writes the ITR value to the appropriate registers. That's the whole vibe. 💫

🦋 SYNOPSIS 🦋

void e1000e_write_itr (struct e1000_adapter *adapter , u32 itr );

Look at her. Iconic signature. Zero drama. Returns void because she doesn't owe you a status code, periodt. 👑

🎀 ARGUMENTS 🎀

  • adapter — the address of the board private structure. Yeah, the board's private business — we're being nosy and we need the pointer to it. 🫶
  • itr — the shiny new ITR value you want to program. This is the actual number going in. 🔥

🧚 DESCRIPTION 🧚

So here's the tea ☕ — e1000e_write_itr first does a lil vibe check on the adapter to figure out whether she's in MSI-X mode.

  • If she is in MSI-X mode: she writes the EITR registers with the ITR value. Plural. The EITR registers get the goods. ✨
  • If she isn't: she just writes the ITR value into the ITR register. Simple. Lowkey elegant. 💅

That's literally it — that's the whole function. It's giving "small but load-bearing" main character energy. 🦋

🌈 SEE ALSO 🌈

Bestie, buckle up, because the SEE ALSO section on this page is a whole friend group 😭 — every single one of these, no skipping:

The kernel file, first of all:

  • Kernel file ./drivers/net/ethernet/intel/e1000e/netdev.c

And the entire entourage:

Like I said. A whole friend group. And yes, we listed every single one, because that's what respect looks like. 🫶💖

🌸 sign-off 🌸

Bestie, that's the page! Sourced from that truncated path that starts ./drivers/net/ethernet/intel/e... and dated October 2026 — so she's fresh, she's current, she's serving. Go forth and write those ITR values, you gorgeous nerd. 🧚✨💜
