STRUCT IDPF_TXQ_GROUP(9)

✨ struct idpf_txq_group(9) ✨

okay bestie, welcome to the kernel API manual 🫶 this one's a struct page from ./drivers/net/ethernet/intel/idpf, and it's literally the group chat for your TX queues 💅 let's get into it.

---

🌸 NAME 🌸

struct idpf_txq_group — no cap, that's the whole name section, they left it blank and honestly? iconic minimalism 🎀

---

🦋 SYNOPSIS 🦋

struct idpf_txq_group {
    struct idpf_vport *vport;
    u16 num_txq;
    struct idpf_tx_queue *txqs[IDPF_LARGE_MAX_Q];
    struct idpf_compl_queue *complq;
    aligned_u64 num_completions_pending;
 };

like, that's the whole squad right there 👑

---

💖 Members 💖

• vport — the back pointer to the vport, aka where this whole thing came from, its origin story fr fr 🧚
• num_txq — how many TX queues are associated with this group. the headcount, basically ✨
• txqs — an array of TX queue pointers, sized IDPF_LARGE_MAX_Q. yes, an array, it's giving main character energy 👑
• complq — the associated completion queue pointer — and bestie, listen: this one is split queue only 🙈
• num_completions_pending — the total number of completions pending for the completion queue, accumulated for all TX queues associated with that completion queue. that's a lot of pending, lowkey 😭

---

🔥 Description 🔥

okay so here's the tea ☕ between singleq and splitq, a txq_group is largely the same except for the complq. that's the one difference, periodt.

in splitq, a single complq is responsible for handling completions for some number of txqs associated in this txq_group. so like, one complq carrying the whole team on its back 💀 slay.
