STRUCT CFG80211_NAN_FUNC_FILTER(9)

💅 struct cfg80211_nan_func_filter(9) — Kernel API Manual 🦋

okay so bestie, welcome to the struct cfg80211_nan_func_filter(9) page, straight out of the Kernel API Manual ✨ this one's short and sweet, so like, drink some water and let's go 🫶

---

🌸 NAME 🌸

struct cfg80211_nan_func_filter — literally a NAN function Rx / Tx filter, that's the whole vibe 💫

---

🎀 SYNOPSIS 🎀

here's the glow-up, told entirely in code, no notes:

struct cfg80211_nan_func_filter {
    const u8 *filter;
    u8 len;
 };

look at her. two members. main character energy, honestly 👑

---

✨ Members ✨

• filter — the content of the filter, like, the actual stuff inside it 💖 it's a const u8 *, so no touching, we respect her boundaries 🙈
• len — the length of the filter 🎯 a u8, which means it's smol, so keep that in mind iykyk

---

lowkey obsessed with how tiny this struct is ngl — but bestie, this is only part one, so don't go anywhere 💜

✨ SEE ALSO ✨

okay bestie, if you're still thirsty for more kernel lore, the whole extended universe lives in <code>./include/net/cfg80211.h</code>. here's every single cross-reference, no cap, exactly as the manual gods intended so you don't miss a single one:
