e1000_reset_adaptive(9)

💖 e1000_reset_adaptive — Kernel API Manual, bestie edition 💖

okay so like. this is a page from the Kernel API Manual, and the star of the show is e1000_reset_adaptive(9) — the little function that puts Adaptive IFS back to its factory-default vibe. it's giving "factory reset but make it networking" and honestly? iconic. 🌸

---

✨ NAME ✨

e1000_reset_adaptive — Resets Adaptive IFS to its default state. no cap, that's literally the whole job. 🎀

---

🦋 SYNOPSIS 🦋

void e1000_reset_adaptive (struct e1000_hw *hw );

returns nothing (void, she gives nothing and that's fine 💅), takes one pointer, and yes the spacing in the original is exactly like that — we do not touch the code, ever. 🔥

---

👑 ARGUMENTS 👑

• hw — Struct containing variables accessed by shared code. that's it. that's the whole argument. it's the struct e1000_hw * from the synopsis, and it's carrying all the shared-code variables, so treat her with respect. 💜

---

⭐ DESCRIPTION ⭐

okay bestie here's the tea 🍵 — call this after e1000_init_hw. like, after after. that's the order and we do not freelance it. 🫶

you may override the IFS defaults, but you do it by setting hw->ifs_params_forced to <italic>true</italic>. sounds chill, right? however 😭 — plot twist — you must initialize all of these first, before you call this function:

• hw->current_ifs_val
• ifs_min_val
• ifs_max_val
• ifs_step_size
• ifs_ratio

⚠️ real talk: if you flip hw->ifs_params_forced to <italic>true</italic> and then forget any one of those five fields, that's on you. the manpage says must, and must means must. 🙈

so: init hardware first, set up your override fields, set the forced flag, then call. in that order. slay in sequence, not in chaos. ✨

and that's the page!! 🧚 from ./drivers/net/ethernet/intel/e... (yes, truncated just like that in the footer), October 2026 edition, closing out with e1000_reset_adaptive(9) one more time for the girls at the back. go reset that Adaptive IFS, bestie, you're gonna ate. 💅✨🍓
