ath5k_hw_get_frame_duration(9)

💖 NAME 💖

okay bestie, meet ath5k_hw_get_frame_duration(9) from the Kernel API Manual. Its whole job is literally: Get tx time of a frame ✨.

---

✨ SYNOPSIS ✨

the signature, verbatim, because we do not mess with code 💅:

int ath5k_hw_get_frame_duration (struct ath5k_hw *ah , enum nl80211_band
band , int len , struct ieee80211_rate *rate , bool shortpre );

---

🎀 ARGUMENTS 🎀

• ah — the struct ath5k_hw 🫶
• band — one of enum nl80211_band 🌈
• len — the frame’s length in bytes, yes bytes bestie 📏
• rate — the struct ieee80211_rate 💫
• shortpre — indicate short preample 🙈 (that’s the page’s spelling, not me being chaotic)

also: it’s spelled shortpre, and the description says “Indicate short preample” — keep that exact vibe 💅

---

🦋 DESCRIPTION 🦋

okay so this one calculates the tx duration of a frame from its rate and length. the original says “given it’s rate and length” — we keep the facts, not the grammar policing 😭.

it also extends ieee80211_generic_frame_duration for non standard bwmodes ✨.
