STRUCT LEAPRAID_IO_UNIT_CTRL_REQ(9)

🦋 struct leapraid_io_unit_ctrl_req(9) 🦋

okay so bestie, this is a page out of the Kernel API Manual, and it's literally all about struct leapraid_io_unit_ctrl_req — the I/O unit control request 💅

---

✨ NAME ✨

struct leapraid_io_unit_ctrl_req — I/O unit control request 🎀

---

🌸 SYNOPSIS 🌸

like, here's the whole shape of it, no cap:

struct leapraid_io_unit_ctrl_req {
    u8 op;
    u8 r1;
    u8 chain_offset;
    u8 func;
    __le16 dev_hdl;
    u8 adapter_para;
    u8 msg_flag;
    u8 r2[6];
    u8 phy_num;
    u8 r3[17];
    __le32 adapter_para_value;
    __le32 adapter_para_value2;
    u8 r4[4];
 };

💖 Members 💖

okay so let's go field by field, main character energy only 👑

• op — the operation code, like the vibe of the whole request ✨
• r1 — reserved. it's giving "don't touch, not for you" 🙈
• chain_offset — the SGE chain offset 🔗
• func — the function code 🧚
• dev_hdl — the device handle, iykyk 🫶
• adapter_para — the adapter parameter selector, literally picking which param we're talking about 🎀
• msg_flag — the message flags 🚩
• r2 — reserved 🌈
• phy_num — the PHY number, okurrr ⭐
• r3 — reserved 💜
• adapter_para_value — the actual value for the adapter parameter, the moment we've all been waiting for 🔥
• adapter_para_value2 — an optional second parameter value. optional!! we love a lowkey bonus field 💅
• r4 — reserved, we stan a respectful reserved field 😌
