UNION DPNI_STATISTICS(9)

💅 union dpni_statistics(9) — Kernel API Manual 🎀

okay so bestie, welcome to the glow-up of union dpni_statistics 💖 this is a Kernel API Manual page, and it's literally the union that describes all the DPNI statistics — like the group chat where every counter comes to spill its numbers ✨

---

🌸 NAME 🌸

union dpni_statistics — a union describing the DPNI statistics. that's it, that's the vibe 🫶

---

✨ SYNOPSIS ✨

here's the whole struct, copied exactly, no cap — every field is iconic in its own way 👑

union dpni_statistics {
    struct {
      u64 ingress_all_frames;
      u64 ingress_all_bytes;
      u64 ingress_multicast_frames;
      u64 ingress_multicast_bytes;
      u64 ingress_broadcast_frames;
      u64 ingress_broadcast_bytes;
    } page_0;
    struct {
      u64 egress_all_frames;
      u64 egress_all_bytes;
      u64 egress_multicast_frames;
      u64 egress_multicast_bytes;
      u64 egress_broadcast_frames;
      u64 egress_broadcast_bytes;
    } page_1;
    struct {
      u64 ingress_filtered_frames;
      u64 ingress_discarded_frames;
      u64 ingress_nobuffer_discards;
      u64 egress_discarded_frames;
      u64 egress_confirmed_frames;
    } page_2;
    struct {
      u64 egress_dequeue_bytes;
      u64 egress_dequeue_frames;
      u64 egress_reject_bytes;
      u64 egress_reject_frames;
    } page_3;
    struct {
      u64 cgr_reject_frames;
      u64 cgr_reject_bytes;
    } page_4;
    struct {

      u64 counter[DPNI_STATISTICS_CNT];
    } raw;
  };

🦋 Members 🦋

🍓 page_0

page_0 — the Page_0 statistics structure. she's the ingress girlie, first page energy 💅

• page_0.ingress_all_frames — ingress frame count, all of them, every single one 💖
• page_0.ingress_all_bytes — ingress byte count, the bytes are byte-ing 🔥
• page_0.ingress_multicast_frames — ingress multicast frame count 🌈
• page_0.ingress_multicast_bytes — ingress multicast byte count ✨
• page_0.ingress_broadcast_frames — ingress broadcast frame count 📣
• page_0.ingress_broadcast_bytes — ingress broadcast byte count 🎀

🍓 page_1

page_1 — the Page_1 statistics structure. now we're on the egress side, main character shift 💫

• page_1.egress_all_frames — egress frame count 👑
• page_1.egress_all_bytes — egress byte count 💜
• page_1.egress_multicast_frames — egress multicast frame count 🌸
• page_1.egress_multicast_bytes — egress multicast byte count 🧚
• page_1.egress_broadcast_frames — egress broadcast frame count 📢
• page_1.egress_broadcast_bytes — egress broadcast byte count ⭐

🍓 page_2

page_2 — the Page_2 statistics structure. this one's the filtered/discarded lore, kind of dramatic ngl 😭

• page_2.ingress_filtered_frames — ingress filtered frame count 🫧
• page_2.ingress_discarded_frames — ingress discarded frame count 💀
• page_2.ingress_nobuffer_discards — ingress discarded frame count due to lack of buffers. yeah, no buffers, tragic 🙈
• page_2.egress_discarded_frames — egress discarded frame count 😔
• page_2.egress_confirmed_frames — egress confirmed frame count ✅

🍓 page_3

page_3 — the Page_3 statistics structure. queue math, we love to see it 📊

• page_3.egress_dequeue_bytes — cumulative count of the number of bytes dequeued from egress FQs 🔥
• page_3.egress_dequeue_frames — cumulative count of the number of frames dequeued from egress FQs ✨
• page_3.egress_reject_bytes — cumulative count of the number of bytes in egress frames whose enqueue was rejected. rejected, not accepted, moving on 💅
• page_3.egress_reject_frames — cumulative count of the number of egress frames whose enqueue was rejected 🚫

🍓 page_4

page_4 — the Page_4 statistics structure: congestion points. congested but make it cute 🚦

• page_4.cgr_reject_frames — number of rejected frames due to congestion point 💔
• page_4.cgr_reject_bytes — number of rejected bytes due to congestion point 😵

🍓 page_5

page_5 — the Page_5 statistics structure: policer. traffic-light couture, honestly iconic 🚥

• page_5.policer_cnt_red — number of red colored frames ❤️
• page_5.policer_cnt_yellow — number of yellow colored frames 💛
• page_5.policer_cnt_green — number of green colored frames 💚
• page_5.policer_cnt_re_red — number of recolored red frames 🎨
• page_5.policer_cnt_re_yellow — number of recolored yellow frames 🌟

🍓 page_6

page_6 — the Page_6 statistics structure. one field, one moment, one legend 🫶

• page_6.tx_pending_frames — total number of frames pending in egress FQs ⏳

🍓 raw

• raw — raw statistics structure, used to index counters 🔢 like the index of the whole friend group fr fr

okay that's the whole page, you ate that 🫶 source is ./drivers/net/ethernet/freesca... and it's dated October 2026, and yes it's still union dpni_statistics(9) — bye bestie, go count some frames 💅✨🎀
