STRUCT BNX2I_ENDPOINT(9)

🧚 struct bnx2i_endpoint(9) — a Kernel API Manual moment

okay bestie, so this is a page from the Kernel API Manual, and it's about struct bnx2i_endpoint — literally the whole vibe of what a tcp connection looks like in NX2 world. no cap.

✨ NAME ✨

struct bnx2i_endpoint — representation of tcp connection in NX2 world. that's it, that's the whole thing 💅

---

🎀 SYNOPSIS 🎀

like, here's the shape of it. don't touch the semicolons, they're doing their job:

struct bnx2i_endpoint {
    struct list_head link;
    struct bnx2i_hba *hba;
    struct bnx2i_conn *conn;
    struct iscsi_endpoint *cls_ep;
    struct cnic_sock *cm_sk;
    u32 hba_age;
    u32 state;
    unsigned long timestamp;
    atomic_t num_active_cmds;
    u32 ec_shift;
    struct qp_info qp;
    struct ep_handles ids;
  #define ep_iscsi_cid    ids.drv_iscsi_cid;
  #define ep_cid          ids.fw_cid;
  #define ep_pg_cid       ids.pg_cid;
    struct timer_list ofld_timer;
    wait_queue_head_t ofld_wait;
 };

💖 Members 💖

• link — the list head that links elements together. it's giving glue energy 🫶
• hba — the adapter this connection belongs to. your connection's home base, fr fr
• conn — the iscsi connection this EP is linked to
• cls_ep — the associated iSCSI endpoint pointer
• cm_sk — the cnic sock struct
• hba_age — the age, used to detect if iscsid issues ep_disconnect after the HBA reset is completed by bnx2i/cnic/bnx2 modules. lowkey a detective 🔍
• state — tracks the offload connection state machine. main character energy honestly
• timestamp — tracks the start time for when the ep begins to connect ⏰
• num_active_cmds — tracks the number of outstanding commands for this ep
• ec_shift — the amount of shift as part of the event coal calc
• qp — QP information
• ids — contains the chip allocated context id & the driver assigned iscsi cid
• ofld_timer — the offload timer, there to detect timeout ⏳
• ofld_wait — a wait queue

🌸 Description 🌸

okay so — this is the Endpoint Structure, which is literally the equivalent of the tcp socket structure. that's the whole description, she's short and she ate 💅✨
