STRUCT IEEE80211_RADIOTAP_HEADER(9)

🌸 NAME 🌸

struct ieee80211_radiotap_header — the base radiotap header, bestie 💅 it's the little guy every radiotap packet starts with, no cap

✨ SYNOPSIS ✨

okay so here's literally the whole shape of it, look:

struct ieee80211_radiotap_header {
    struct {
      uint8_t it_version;
      uint8_t it_pad;
      __le16 it_len;
      __le32 it_present;
    };
    __le32 it_optional[];
 };

periodt, that's the struct 💖

🎀 Members 🎀

• {unnamed_struct} — anonymous 🫶 yeah it's just vibing there with no name, that's the whole description, iconic honestly
• it_version — the radiotap version, and it's always 0. always. don't come for her with anything else 🙈
• it_pad — padding (or alignment) 🦋 she's just here to keep things lined up, main character energy of the humble variety
• it_len — the overall radiotap header length ✨ the whole thing, not a piece of it
• it_present — the (first) present word 👑 "first" is doing real work in that sentence, iykyk
• it_optional — all the remaining presence bitmaps 🌈 the rest of the squad, showing up after the first one
