STRUCT MUX_ADB(9)

💖 struct mux_adb(9) 💖

okay bestie, welcome to the Kernel API Manual page for struct mux_adb 💅 this is the structure of state of a single UL data block, and it's lowkey iconic. no cap.

✨ NAME ✨

struct mux_adb — structure of state of a single UL data block 🦋

🌈 SYNOPSIS 🌈

struct mux_adb {
    struct sk_buff *dest_skb;
    u8 *buf;
    struct mux_adgh *adgh;
    struct sk_buff *qlth_skb;
    u32 *next_table_index;
    struct sk_buff_head free_list;
    int size;
    u32 if_cnt;
    u32 dg_cnt_total;
    u32 payload_size;
    struct mux_adth_dg
dg[IPC_MEM_MUX_IP_SESSION_ENTRIES][IPC_MEM_MAX_UL_DG_ENTRIES];
    struct mux_qlth *pp_qlt[IPC_MEM_MUX_IP_SESSION_ENTRIES];
    struct mux_adbh *adbh;
    u32 qlt_updated[IPC_MEM_MUX_IP_SESSION_ENTRIES];
    u32 dg_count[IPC_MEM_MUX_IP_SESSION_ENTRIES];
 };

🎀 Members 🎀

• dest_skb — current UL skb for the data block. yes bestie, that one 💫
• buf — ADB memory. literally the ADB memory.
• adgh — ADGH pointer. pointing at ADGH, periodt.
• qlth_skb — QLTH pointer. it's giving pointer energy 🫶
• next_table_index — pointer to next table index. next!
• free_list — list of alloc. ADB for the UL sess. that's the exact vibe.
• size — size of the ADB memory. iconic measurement moment 📏
• if_cnt — statistic counter. counting stats, slay.
• dg_cnt_total — datagram count total. total total, not a drill.
• payload_size — Payload Size. capital S because it said so, iykyk.
• dg — datagram table. table but make it datagrams ✨
• pp_qlt — pointers to hold Queue Level Tables of session. hold them gently 💖
• adbh — ADBH pointer. another pointer, another moment.
• qlt_updated — queue level table updated. updated, bestie.
• dg_count — datagram count. count 'em 👑
