STRUCT IWL_MVM_LINK_STA(9)

💅 struct iwl_mvm_link_sta(9) 💅

okay so bestie, this is a page straight out of the Kernel API Manual ✨ and it's literally all about struct iwl_mvm_link_sta — the link-specific deets of a station. yes, that station. we're getting into the per-link gossip today 🎀

---

✨ NAME ✨

struct iwl_mvm_link_sta — link specific parameters of a station 🫶

---

🌸 SYNOPSIS 🌸

here's the shape of it, no cap, copied exactly:

struct iwl_mvm_link_sta {
    struct rcu_head rcu_head;
    u32 sta_id;
    union {
      struct iwl_lq_sta_rs_fw rs_fw;
      struct iwl_lq_sta rs_drv;
    } lq_sta;
    u16 orig_amsdu_len;
    u8 avg_energy;
 };

like, that's the whole vibe check of the struct 💖

🦋 Members 🦋

okay now the main characters, one by one 👑

• rcu_head — used for freeing the data. it's giving cleanup crew energy 🧹
• sta_id — the index of the station in the fw. that's its little fw ID badge 🎀
• lq_sta — holds rate scaling data, either for the case when RS is done in the driver — rs_drv — or in the FW — rs_fw. two paths, one union, both iconic 💅
• orig_amsdu_len — used to save the original amsdu_len when it is changed via debugfs. and if it's set to 0, it means that it's not set via debugfs. lowkey important, don't forget it 🙈
• avg_energy — energy as reported by FW statistics notification. it's literally the station's aura reading ⚡
