ieee80211_e...imeout_in_us(9)

👑 ieee80211_eml_trans_timeout_in_us(9) — the Kernel API Manual, bestie edition 💅

okay so this is a page straight out of the Kernel API Manual, and it's about ieee80211_eml_trans_timeout_in_us(9) — a tiny little helper that, like, pulls one specific number out of a Wi-Fi Multi-Link blob. it's giving "small function, big responsibilities" energy fr fr. let's get into it 🫶

---

✨ NAME ✨

ieee80211_eml_trans_timeout_in_us — Fetch the EML Transition timeout value in microseconds 🌸

like, the whole personality of this function is "give me the EML Transition timeout and give it to me in microseconds" and honestly? iconic. no notes.

---

🦋 SYNOPSIS 🦋

u32 ieee80211_eml_trans_timeout_in_us(u16 eml_cap);

that's it. one arg, one u32 back. so clean, so slay 💖

---

🎀 ARGUMENTS 🎀

• eml_cap — the EML capabilities field value, taken from the common info field of the Multi-link element. that's the raw capability bits you're handing over, and the function is gonna go read them for you 💅

---

⭐ RETURN ⭐

it returns the EML Transition timeout (in microseconds ⏱️) that's encoded in the EML Capabilities field. that's the whole vibe — you pass in the caps, you get back a timeout, in us, periodt.

like… the _in_us squad at the bottom? obsessed. they're all siblings and they all return microsecond values. iykyk 💜

lowkey reminder: eml_cap is supposed to be the EML capabilities field value from the common info field of the Multi-link element — that's the source of truth here, don't go handing it something else 🙈

---

and that's the page!! 🎀 source situation: it lives under ./include/linux, the manual is stamped October 2026, and it's filed as ieee80211_e...imeout_in_us(9) — yes the title is truncated in the header, that's just how the manpage printer does it, no cap 😭🫶 catch you in the next one bestie 💖✨
