STRUCT IONIC_RXQ_SG_DESC(9)

💅 struct ionic_rxq_sg_desc(9) — the Kernel API Manual, but make it make sense

okay so bestie, welcome to the struct ionic_rxq_sg_desc(9) page 💖 this is straight out of the Kernel API Manual and it's lowkey short but it's a real one. no cap.

---

✨ NAME ✨

struct ionic_rxq_sg_desc — the Receive scatter-gather (SG) list 🎀 (yes, SG means scatter-gather, iykyk)

---

🌸 SYNOPSIS 🌸

here's the whole shape of it, verbatim, don't @ me:

struct ionic_rxq_sg_desc {
  #define IONIC_RX_MAX_SG_ELEMS           8;
  #define IONIC_RX_SG_DESC_STRIDE         8;
    struct ionic_rxq_sg_elem elems[IONIC_RX_SG_DESC_STRIDE];
 };

like. it's giving "small but mighty". the struct holds an array and there are two #defines hanging out inside the block, and yes we are keeping them exactly where they are 🔥

---

🦋 Members 🦋

• elems — the scatter-gather elements themselves, bestie. that's the whole vibe. every element in this array is a struct ionic_rxq_sg_elem, sized by IONIC_RX_SG_DESC_STRIDE (which is 8, iconically) 💅

ngl there is nothing dangerous or deprecated hiding in here — it's just a struct with an array of SG elements. no gotchas. just vibes and pointers-ish. 💜

and that's the page!! source/version situation for the sign-off: this came from ./drivers/net/ethernet/pensand... and it's dated October 2026, filed under struct ionic_rxq_sg_desc(9) ⭐ that's the whole thing bestie, you ate, periodt 🧚‍♀️💖
