STRUCT IDPF_RXQ_GROUP(9)

💖 struct idpf_rxq_group(9) — the kernel API manual, but make it make sense 🎀

okay so bestie, we're in the Kernel API Manual today and the vibe is extremely "Intel idpf driver internals." no cap, this one's a struct, and she's got a union in her. let's go 💅

---

✨ NAME ✨

struct idpf_rxq_group — literally the struct that holds your RX queue group together 🫶

---

🌸 SYNOPSIS 🌸

struct idpf_rxq_group {
    struct idpf_vport *vport;
    union {
      struct {
        u16 num_rxq;
        struct idpf_rx_queue *rxqs[IDPF_LARGE_MAX_Q];
      } singleq;
      struct {
        u16 num_rxq_sets;
        u16 num_bufq_sets;
        struct idpf_rxq_set *rxq_sets[IDPF_LARGE_MAX_Q];
        struct idpf_bufq_set *bufq_sets;
      } splitq;
    };
 };

like, look at her. two whole personalities in one union. main character energy fr fr 💀

🦋 Members 🦋

okay so member by member, group chat style:

• vport — the vport back pointer. she knows where she came from 💖
• {unnamed_union} — anonymous. no name, all mystery, we respect it 🙈
• singleq — the struct with all the single queue related members ✨
  • singleq.num_rxq — the number of RX queues associated 👑
  • singleq.rxqs — array of RX queue pointers, iconic ⭐
• splitq — the struct with all the split queue related members 🌈
  • splitq.num_rxq_sets — the number of Buffer queue sets (that's what the page says bestie, I'm just the messenger 😭)
  • splitq.rxq_sets — array of RX queue sets 🎀
  • splitq.bufq_sets — Buffer queue set pointer 🔥

ngl, splitq.num_bufq_sets is sitting right there in the struct up top but the members list doesn't give her a blurb. not me noticing 👀 — I'm just not gonna make up lore that isn't in the source.

---

💜 Description 💜

so here's the tea 🍓:

in singleq mode, an rxq_group is simply an array of rxqs. that's it. that's the whole personality. lowkey refreshing.

in splitq mode, an rxq_group contains all the rxqs, bufqs and refillqs needed to manage buffers in splitq mode. she's doing the absolute most and honestly? ate. 💅

and that's the whole page, bestie 🧚 no crumbs left behind. this one lives in ./drivers/net/ethernet/intel/idpf, dated October 2026, and it's struct idpf_rxq_group(9) — periodt. 💖✨
