STRUCT IWL_MVM_REORDER_BUFFER(9)

💖 struct iwl_mvm_reorder_buffer(9) 💖

okay so bestie, welcome to the <pink>Kernel API Manual</pink> ✨ — this is the page for struct iwl_mvm_reorder_buffer(9), which is, and I cannot stress this enough, the per ra/tid/queue reorder buffer. yes. all three. at once. she's booked and busy 💅

---

🌸 NAME 🌸

struct iwl_mvm_reorder_buffer — the per ra/tid/queue reorder buffer 🎀

Like, literally what it says on the tin. no notes.

---

✨ SYNOPSIS ✨

here's the whole glow-up, copy it exactly bestie, character for character:

struct iwl_mvm_reorder_buffer {
    u16 head_sn;
    u16 num_stored;
    int queue;
    bool valid;
    spinlock_t lock;
 };

that's her. that's the whole struct. five fields and a dream 🦋

🫶 Members 🫶

okay let's go field by field, because every single one of these matters:

• head_sn — the reorder window head sn 💫 (that's the head sequence number, she's the one setting the tone for the window, main character energy fr)
• num_stored — number of mpdus stored in the buffer 🍓 (yes bestie, we're counting them. all of them.)
• queue — the queue that this reorder buffer belongs to 👑 (every reorder buffer has her own queue, iykyk)
• valid — reordering is valid for this queue ⭐ (a whole bool just to tell you if it's valid. love that for us.)
• lock — spinlock that protects the reorder buffer internal state 🔥 (do NOT touch the internal state without her, she WILL notice 💀)

quick vibe check: all of these are literal names from the original page, so don't go renaming them thinking you're being helpful. you're not. leave the identifiers alone bestie 🙈
