STRUCT MUX_ACB(9)

✨ struct mux_acb(9) ✨

okay so this is a page straight out of the Kernel API Manual, bestie — welcome to the struct mux_acb era, we're talking about the Structure of Temporary ACB state and honestly? iconic. temporary queen behavior. 🎀

---

🌸 NAME 🌸

struct mux_acb — the structure that holds all your temporary ACB state. yes. that's the whole vibe. 💅

---

🦋 SYNOPSIS 🦋

here's the whole shape of it, copy it exactly, don't be weird about it:

struct mux_acb {
    struct sk_buff *skb;
    int if_id;
    u8 *buf_p;
    u32 wanted_response;
    u32 got_response;
    u32 cmd;
    union mux_cmd_param got_param;
 };

literally just seven little fields and a dream. 🫶

---

💖 Members 💖

okay now let's meet the cast, one member at a time, main character energy only:

• skb — the UL skb that's actually being used. that's it. that's the field. 🧚
• if_id — the session id. iykyk. 🌈
• buf_p — the command buffer. points at your command, doing its little pointer thing. ⭐
• wanted_response — the Wanted Response. the one we're manifesting. 🙈
• got_response — the Got Response. the one that actually showed up. 😭
• cmd — the command. lowercase, humble, essential. 💀
• got_param — the received command/response parameter. lowkey the most interesting one ngl. 🔥

---

👑 SEE ALSO 👑

so this whole thing lives in the kernel file ./drivers/net/wwan/iosm/iosm_ipc_mux.h, and here's the full squad it runs with — no cap, every single one:

• union mux_cmd_param(9)
• struct mux_adth_dg(9)
• struct mux_qlth_ql(9)
• struct mux_qlth(9)
• struct mux_adb(9)
• struct iosm_mux(9)
• ipc_mux_init(9)
• ipc_mux_deinit(9)
• ipc_mux_check_n_restart_tx(9)
• ipc_mux_get_active_protocol(9)
• ipc_mux_open_session(9)
• ipc_mux_close_session(9)
• ipc_mux_get_max_sessions(9)

like, the whole friend group. go read them too, bestie, fr fr. 💜

that's the entire page, you ate that. go forth and structure your temporary ACB state responsibly. periodt. 💅✨

bye bestie! this lil masterpiece comes to you from ./drivers/net/wwan/iosm, dated October 2026, and it's filed under struct mux_acb(9) — mwah, love that for us. 🍓🦋💖
