ENUM IEEE80211_SDATA_STATE_BITS(9)

💖 enum ieee80211_sdata_state_bits — virtual interface state bits 💖

okay bestie so this one is from the Kernel API Manual, section 9, and it's literally just a lil enum that keeps track of what mood your virtual interface is in rn. three states, no cap. 🦋

---

✨ NAME ✨

enum ieee80211_sdata_state_bits — virtual interface state bits 🌸

---

🎀 SYNOPSIS 🎀

enum ieee80211_sdata_state_bits {
    SDATA_STATE_RUNNING ,
    SDATA_STATE_OFFCHANNEL ,
    SDATA_STATE_OFFCHANNEL_BEACON_STOPPED

};

that's it, that's the whole vibe. three members, very demure, very mindful. 💅

---

🌈 Constants 🌈

• SDATA_STATE_RUNNING — the virtual interface is up & running 💖 and this mirrors netif_running but it's kept separate so interface type change handling still works while the interface is up. like, they're twins but not the same person, iykyk ✨
• SDATA_STATE_OFFCHANNEL — this interface is currently in offchannel mode rn, so the queues are stopped 😭 she's off doing her own thing, the queues are just waiting at home.
• SDATA_STATE_OFFCHANNEL_BEACON_STOPPED — beaconing was stopped because of offchannel 🌸 gets reset when offchannel returns. she'll be back, no worries 🫶
