ENUM IWL_SAP_NOTIF_LINK_DOWN_TYPE(9)

💅 enum iwl_sap_notif_link_down_type (9) 💅

okay so this is a page from the Kernel API Manual and it's lowkey just a tiny baby enum, but we're gonna give it the full main-character treatment anyway, because that's what it deserves 🫶

---

✨ NAME ✨

enum iwl_sap_notif_link_down_type — the little enum that's used in &struct iwl_sap_notif_host_link_down 💖 that's literally its whole job and honestly? iconic.

---

🌸 SYNOPSIS 🌸

bestie, here's the whole thing, exactly as it appears, no cap:

enum iwl_sap_notif_link_down_type {
    HOST_LINK_DOWN_TYPE_NONE ,
    HOST_LINK_DOWN_TYPE_TEMPORARY ,
    HOST_LINK_DOWN_TYPE_LONG

};

like. three constants. that's it. that's the enum. slay 💅

🎀 Constants 🎀

okay so time for the vibe check on each of the three members:

• HOST_LINK_DOWN_TYPE_NONE — what does it do? TBD 😭 yeah. that's the whole description. the docs said "we'll get to it" and then never got to it. fr fr it's giving unfinished homework.
• HOST_LINK_DOWN_TYPE_TEMPORARY — also TBD 🙈 same energy. temporary by name, temporararily undocumented by nature.
• HOST_LINK_DOWN_TYPE_LONG — and yeah, TBD again 💀 all three are TBD, ngl this is the most mysterious trio in the whole header file and I kind of respect it.

⚠️ heads up bestie: the original docs literally just say TBD for all three of these — so I'm not gonna sit here and make up behaviour for you. no invented lore on my watch 👑 if the kernel docs won't say it, neither will I.

okay that's the whole page bestie, love u, bye 🫶✨

sign-off time 🎀 this one came from ./drivers/net/wireless/intel/i... and it's dated October 2026 — so yeah, she's from the future, we stan a forward-thinking enum 💜
