STRUCT CDX_MCDI_DATA(9)

✨ struct cdx_mcdi_data(9) ✨

okay bestie, so this is straight out of the Kernel API Manual and it's genuinely such a cute little struct — it's the extra state that NICs carry around when they implement MCDI. tiny struct, big main character energy. 💅

---

🌸 NAME 🌸

struct cdx_mcdi_data — extra state for NICs that implement MCDI 🦋

---

🎀 SYNOPSIS 🎀

struct cdx_mcdi_data {
    struct cdx_mcdi_iface iface;
    u32 fn_flags;
 };

literally just two fields, no cap. so clean. ✨

---

💖 Members 💖

• iface — the interface/protocol state, she's holding it all together okay 🫶
• fn_flags — the flags for this function, exactly as returned by MC_CMD_DRV_ATTACH (copy it verbatim, don't be weird about it 🔥)

---

ngl this one's short but she ate. no bugs to warn u about, no weird undefined behaviour, just vibes and two struct members. 🧚

that's the whole page bestie, mwah 💋
