ieee80211_rts_duration(9)

💅 ieee80211_rts_duration — get the duration field for an RTS frame

okay bestie, welcome to the Kernel API Manual, section 9, where we hang out with the networking girlies 🫶. This little function is ieee80211_rts_duration, and honestly? It's giving "small but crucial." ✨

---

✨ NAME ✨

ieee80211_rts_duration — get the duration field for an RTS frame 💌

---

🌸 SYNOPSIS 🌸

__le16 ieee80211_rts_duration (struct ieee80211_hw *hw , struct
ieee80211_vif *vif , size_t frame_len , const struct ieee80211_tx_info
*frame_txctl );

---

🎀 ARGUMENTS 🎀

• hw — the pointer you got from ieee80211_alloc_hw. like, the whole hardware vibe check. 💻
• vif — a struct ieee80211_vif pointer, straight from the add_interface callback. get it from the source, diva. 🌈
• frame_len — the length of the frame that's gonna be protected by the RTS. yes, protected, like it's got bodyguards. 🛡️
• frame_txctl — the struct ieee80211_tx_info of the frame. the receipts, basically. 🧾

---

🦋 DESCRIPTION 🦋

okay so here's the situation 👀: if the RTS is generated in firmware, but the host system has to provide the duration field, then the low-level driver uses this function to receive that duration field value — and it comes through in little-endian byteorder, no cap. 🔥

so like, firmware makes the frame, but you still gotta hand over the timing info. teamwork. slay. 💅

---

👑 RETURN 👑

The duration. that's it. that's the whole vibe. ⭐

buckle up bestie, this reference list is literally the entire header file and half the mac80211 universe. not me listing every single one 😭 — but I will, because we don't skip entries in this house. 🏠✨

so yeah, that's the whole page, bestie 🌸. this one lives in ./include/net and the doc stamp says October 2026, from the Kernel API Manual (section 9, obvs). go forth and get those durations. mwah 💋🦋💜
