STRUCT MPI3MR_BSG_PACKET(9)

okay bestie, this is struct mpi3mr_bsg_packet(9) from the Kernel API Manual 💖 and we're getting into the generic bsg data structure for all supported requests. no cap, every field is here.

✨ NAME ✨

struct mpi3mr_bsg_packet — generic bsg data structure for all supported requests . 🫶

🌸 SYNOPSIS 🌸

the whole struct, literally:

       struct mpi3mr_bsg_packet {
           __u8 cmd_type;
           __u8 rsvd1;
           __u16 rsvd2;
           __u32 rsvd3;
           union {
             struct mpi3mr_bsg_drv_cmd drvrcmd;
             struct mpi3mr_bsg_mptcmd mptcmd;
           } cmd;
        };

🎀 Members 🎀

• cmd_type — represents drvrcmd or mptcmd 💅
• rsvd1 — Reserved
• rsvd2 — Reserved
• rsvd3 — Reserved
• cmd.drvrcmd — driver request structure
• cmd.mptcmd — mpt request structure

reserved fields stay reserved, bestie — no side quests, no extra meaning 🙈
