ieee80211_new_mesh_header(9)

💅 ieee80211_new_mesh_header(9) — like, the mesh header maker ✨

okay so bestie, welcome to the Kernel API Manual 🎀 this one's a kernel function — ieee80211_new_mesh_header — and it's literally just here to spin up a brand new mesh header for you. no cap. 🦋

---

✨ NAME ✨

ieee80211_new_mesh_header — create a new mesh header 🌸

---

🫶 SYNOPSIS 🫶

unsigned int ieee80211_new_mesh_header (struct ieee80211_sub_if_data
*sdata , struct ieee80211s_hdr *meshhdr , const char *addr4or5 , const
char *addr6 );

that's the whole vibe check right there 👑

---

💖 ARGUMENTS 💖

• sdata — the mesh interface you're gonna use 🧚 she's the main character here, fr fr
• meshhdr — an uninitialized mesh header. yep, uninitialized — she hasn't been born yet, you're giving her life 💀✨
• addr4or5 — the 1st address in the ae header. so like, she may correspond to address 4 (if addr6 is NULL) or address 5 (if addr6 is present). also she may be NULL — no pressure bestie 🙈
• addr6 — the 2nd address in the ae header, and she corresponds to addr6 of the mesh frame 🎀 lowkey iconic

🌈 RETURN 🌈

the header length 💅 that's it, that's the answer. slay.
