STRUCT IWL_MAC_CLIENT_DATA(9)

💅 struct iwl_mac_client_data(9) 💅

okay so bestie, welcome to the glow-up of the Kernel API Manual, section 9 — literally the whole page is about struct iwl_mac_client_data, and it's giving "configuration data for client MAC context" ✨ like, that's its whole NAME-brand moment, no cap.

---

🌸 NAME 🌸

struct iwl_mac_client_data — the configuration data for the client MAC context. that's it, that's the vibe 🎀

---

✨ SYNOPSIS ✨

here's the whole struct, exactly as it lives, don't touch a single character bestie:

struct iwl_mac_client_data {
    u8 is_assoc;
    u8 esr_transition_timeout;
    __le16 medium_sync_delay;
    __le16 assoc_id;
    __le16 reserved1;
    __le16 data_policy;
    __le16 reserved2;
    __le32 ctwin;
};

---

🦋 Members 🦋

okay, member-by-member tour, let's go 💖

• is_assoc — 1 if we're in the associated state, 0 if we're literally not. simple as that 🫶
• esr_transition_timeout — the timeout the AP requires for the eSR transition. heads up though: this is only available from version 2 of the command 👑. the value comes from the EMLSR transition delay in the EML Capabilities subfield. iykyk.
• medium_sync_delay — the value exactly as it appears in P802.11be_D2.2 Figure 9-1002j. like, go look at the figure, it's right there 📖
• assoc_id — the unique ID the AP hands out during association. your little association nametag 🎀
• reserved1 — alignment. that's the whole job. sit there and align 💀
• data_policy — see enum iwl_mac_data_policy. go check it out bestie 👀
• reserved2 — alignment again. iconic reserved behavior honestly 🙈
• ctwin — client traffic window in TU (that's the period after TBTT when GO is present). and 0 means there's literally no CT window at all. zero, nada, no window 🪟❌
