STRUCT IWL_MLD_LINK_STA(9)

✨ struct iwl_mld_link_sta — the link-level station 💅

okay so bestie, this is a page from the Kernel API Manual (the struct iwl_mld_link_sta(9) one, iykyk) and we're gonna get you so comfy with it. it's giving "one link, one station, one vibe" and honestly? iconic. 🎀

🌸 NAME 🌸

struct iwl_mld_link_sta — the link-level station, fr fr

---

🦋 SYNOPSIS 🦋

like, here's the literal shape of the thing, no notes:

struct iwl_mld_link_sta {
    struct {
      struct ieee80211_key_conf *rx_igtk;
      u32 last_rate_n_flags;
      bool in_fw;
      s8 signal_avg;
    };
    struct rcu_head rcu_head;
    u32 fw_id;
 };

yes there's an anonymous struct in there. yes it's a whole mood. moving on 💖

🧚 Members 🧚

• {unnamed_struct} — anonymous 🫶 literally no name, just vibes (and by vibes we mean the four fields right below it).
• rx_igtk — okay so this one's a little dramatic: the FW can only have one IGTK for RX at a time, but mac80211 will have two. so this field tracks the one IGTK that currently exists in FW, so we can go remove it there when a new one gets installed. it's giving "there can only be one" energy 😭 it's a struct ieee80211_key_conf * btw.
• last_rate_n_flags — the rate_n_flags from the last iwl_tlc_update_notif. that's it, that's the whole field, u32 and thriving ✨
• in_fw — whether the link STA is uploaded to the FW (false during restart, bestie — remember that part, it matters 💀). bool.
• signal_avg — the signal average coming from the firmware. s8. it's out here measuring the whole vibe of your signal 🌈
• rcu_head — an RCU head for freeing this object. it's the cleanup crew, struct rcu_head, and we respect it 👑
• fw_id — the FW id of this link sta. u32. its little government name 🪪

💜 Description 💜

so what is this? it represents the link-level sta — the driver-level equivalent to the ieee80211_link_sta. that's the whole main character energy of it: same idea, but the driver's version 💅 slay.

⭐ lowkey a reminder: this page lives under ./drivers/net/wireless/intel/i... (the path gets cut off in the footer, that's just how it is, no cap) and it's dated October 2026. the whole page is titled struct iwl_mld_link_sta(9) — that's your source & version, periodt. 💖

and that's the whole page, bestie — you ate that 🍓✨ bye! 😭💅
