ENUM IWL_LINK_CTX_FLAGS(9)

💖 enum iwl_link_ctx_flags(9) 💖

okay so bestie, this is a page from the Kernel API Manual and it's literally all about enum iwl_link_ctx_flags — yes that's the link context flags 🎀. It lives in the kernel docs, it's giving very much "driver internals but make it cute", and we're gonna go through every single one of these flags together. no skipping, no cap. 🦋

---

✨ SYNOPSIS ✨

here's the whole enum, exactly as it is, look at her:

enum iwl_link_ctx_flags {
    LINK_FLG_BSS_COLOR_DIS ,
    LINK_FLG_MU_EDCA_CW ,
    LINK_FLG_RU_2MHZ_BLOCK ,
    LINK_FLG_NDP_FEEDBACK_ENABLED ,
    LINK_FLG_NPCA ,
    LINK_FLG_DPS ,
    LINK_FLG_MLPM ,
    LINK_FLG_DUO

};

like, she's a whole vibe. eight constants, all iconic, all doing something. 💅

🌸 Constants 🌸

okay so here's the tea on each one, one by one, no gatekeeping:

• LINK_FLG_BSS_COLOR_DIS — BSS color disable, meaning don't use the BSS color for the RX filter, and instead use MAC header enabled AGG — so both BACK and non-BACK frames go in a single AGG. 🫶
• LINK_FLG_MU_EDCA_CW — this one indicates that there's an element of MU EDCA parameter set, i.e. the backoff counters for trig-based ACs. yes, that's the actual description, I'm not paraphrasing the technical bits bestie 😭
• LINK_FLG_RU_2MHZ_BLOCK — indicates that 26-tone RU OFDMA transmission are not allowed (because there are OBSS that might classify such transmissions as radar pulses). like, rude of them but okay 💀
• LINK_FLG_NDP_FEEDBACK_ENABLED — marks support for NDP feedback and change of threshold. ⭐
• LINK_FLG_NPCA — NPCA enabled. short, sweet, slays. ✨
• LINK_FLG_DPS — the AP is a DPS assisting AP. 👑
• LINK_FLG_MLPM — the AP supports UHR multi-link PM. 🌈
• LINK_FLG_DUO — the AP supports UHR DUO. 🔥

that's all eight, all accounted for, nobody left on read. 💜

like I said. the whole group chat. 😭🫶

ngl bestie, this is kernel wireless driver internals — if you're poking at these flags you're already deep in the iwlwifi sauce and I'm proud of you. 🧚
