ENUM IEEE80211_SUB_IF_DATA_FLAGS(9)

💅 enum ieee80211_sub_if_data_flags — virtual interface flags ✨

okay bestie, so this is the manual page for enum ieee80211_sub_if_data_flags, live from the <mint>Kernel API Manual</mint>. we're talking about the flags that hang out on a virtual interface in mac80211 land. it's giving very niche kernel energy and honestly? kind of iconic. 🫶

You'll find all this goodness in the kernel file <pink>./net/mac80211/ieee80211_i.h</pink> — that's where the enum lives, no cap. 💖

---

🌸 SYNOPSIS 🌸

like, here's the exact shape of the thing, bestie — every constant, character for character:

enum ieee80211_sub_if_data_flags {
    IEEE80211_SDATA_ALLMULTI,
    IEEE80211_SDATA_DONT_BRIDGE_PACKETS,
    IEEE80211_SDATA_DISCONNECT_RESUME,
    IEEE80211_SDATA_IN_DRIVER,
    IEEE80211_SDATA_DISCONNECT_HW_RESTART

};

---

✨ CONSTANTS ✨

okay so these are the actual flag girlies, one by one — memorise them, they're on the test:

• IEEE80211_SDATA_ALLMULTI — this interface is lowkey greedy and wants all the multicast packets. every last one. periodt. 💅
• IEEE80211_SDATA_DONT_BRIDGE_PACKETS — this one's giving boundary issues 💀 — it means bridge packets between associated stations and deliver multicast frames both back to the wireless media and to the local net stack. like, both places. no cap.
• IEEE80211_SDATA_DISCONNECT_RESUME — disconnect after resume. that's it. that's the vibe. 😭
• IEEE80211_SDATA_IN_DRIVER — indicates the interface was added to the driver. she's officially in. 👑
• IEEE80211_SDATA_DISCONNECT_HW_RESTART — disconnect after hardware restart recovery. hardware said "we back" and the interface said "aight, disconnecting." 🔥

bestie reminder: every single one of those constants, the exact names, the exact order in the enum — keep them close. iykyk. 🧚
