STRUCT IONIC_RXQ_SG_ELEM(9)

💅 struct ionic_rxq_sg_elem(9) — like, the Kernel API Manual era 🦋

okay bestie, sit down, hydrate, and let me tell you about struct ionic_rxq_sg_elem</p> — a little struct from the Kernel API Manual section 9 that is literally the receive scatter-gather (SG) descriptor element. tiny struct, big job. periodt. ✨

---

🌸 NAME 🌸

struct ionic_rxq_sg_elem — the Receive scatter-gather (SG) descriptor element 💖

---

🎀 SYNOPSIS 🎀

struct ionic_rxq_sg_elem {
    __le64 addr;
    __le16 len;
    __le16 rsvd[3];
 };

no cap that's the whole thing. she's small but she's everything. 🫶

---

🧚 Members 🧚

• addr — the DMA address of the SG element data buffer. like, the actual address-address, where the data lives. 📍
• len — length of the SG element data buffer, in bytes. the classic "how much" of it all. 📏
• rsvd — reserved byte(s). not for you, bestie. hands off. 🙈 this is the reserved corner of the struct, we do not touch it, we do not perceive it.

first up, the kernel file this all lives in: ./drivers/net/ethernet/pensando/ionic/ionic_if.h — go read it, iykyk 📖💜

that's the whole group chat, everybody showed up. 🔥

real talk though: rsvd is reserved, meaning the kernel owns it and you don't. no poking, no prodding, no "but what if". 💀

and that's the whole page, bestie! source is ./drivers/net/ethernet/pensand... (the truncation is canon, don't @ me 😭), dated October 2026, filed under struct ionic_rxq_sg_elem(9) in your fave Kernel API Manual. go forth and scatter-gather responsibly. mwah 💋🌈⭐
