STRUCT IONIC_TXQ_SG_ELEM(9)

💅 struct ionic_txq_sg_elem(9) — the transmit scatter-gather descriptor element 💅

okay bestie, welcome to the Kernel API Manual ✨ and to literally the littlest struct in the ionic driver. no cap, this is the transmit scatter-gather (SG) descriptor element, and she's tiny but she's everything 🎀

---

🌸 NAME 🌸

struct ionic_txq_sg_elem — Transmit scatter-gather (SG) descriptor element 🦋

like, she's one (1) element. one singular little descriptor. and she eats. 🔥

---

✨ SYNOPSIS ✨

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

that's the whole vibe. four fields, one of them is literally just filler. main character energy honestly 👑

🫶 Members 🫶

• addr — DMA address of the SG element data buffer 💖 like, this is where the buffer lives in DMA land. the actual address. the location. the spot. slay.
• len — Length of SG element data buffer, in bytes 📏 measured in bytes bestie, not vibes.
• rsvd — reserved byte(s) 🙈 she doesn't do anything, she's just there holding space, we respect her.

not me writing out every single cross-reference because the rule is keep every detail 😭 and I did. fr fr.

and that's the page bestie!! 🎀 she comes from ./drivers/net/ethernet/pensand... and she's dated October 2026 — so mark your calendar, this struct is literally from the future 💜✨ mwah, go read the rest of the ionic header, ily 🫶🌟
