ieee80211_m..._frame_flags(9)

💖 ieee80211_mps_set_frame_flags(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one's a little mesh-networking baddie from the mac80211 world and she is, like, so specific. it's giving "small function, big responsibility" energy fr fr 🫶

---

🌸 NAME 🌸

ieee80211_mps_set_frame_flags — sets the mesh PS flags in the FC (and also in the QoS Control), no cap 💅

---

✨ SYNOPSIS ✨

void ieee80211_mps_set_frame_flags(struct ieee80211_sub_if_data *sdata,
                                   struct sta_info *sta,
                                   struct ieee80211_hdr *hdr);

like yes she returns void, she's not here to give you answers, she's here to do the thing and dip 🙈

---

🎀 ARGUMENTS 🎀

• sdata — the local mesh subif 🧚 that's your little corner of the mesh world
• sta — the mesh STA 👑 one (1) station, being her main character self
• hdr — the 802.11 frame header 📨 the actual envelope we're decorating with flags

---

🦋 DESCRIPTION 🦋

go read IEEE802.11-2012 8.2.4.1.7 and 8.2.4.5.11 💀 yeah, that's the whole description. the spec said iykyk and honestly? iconic of it. go look up those sections if you want the full lore, bestie 📚

---

💀 NOTE 💀

listen close because this part matters: sta must be given when an individually-addressed QoS frame header is being handled 😭 but for group-addressed frames and management frames, it is not used 🚫 so don't come for her if sta is a whole nothingburger in those cases — that's literally by design 🌈
