STRUCT EF4_HW_STAT_DESC(9)

💅 struct ef4_hw_stat_desc(9)

okay so bestie, welcome to the Kernel API Manual ✨ this one's a lil struct page and it's literally the cutest little descriptor you ever did see 🎀

---

🌸 NAME 🌸

struct ef4_hw_stat_desc — no cap, it's the Description of a hardware statistic 🫶

---

✨ SYNOPSIS ✨

here's the whole vibe, character for character, don't touch it:

struct ef4_hw_stat_desc {
    const char *name;
    u16 dma_width;
    u16 offset;
 };

---

🦋 Members 🦋

so like, three members, three lil besties, each one iconic in her own way 💖

• name — this is the name of the statistic as visible through ethtool 👑 or, plot twist, NULL if it should not be exposed 🙈 (yes, some stats are main-character-only, we keep those private)
• dma_width — the width, in bits 🔥 and it's 0 for the non-DMA statistics, iykyk
• offset — the offset within stats 🎯 and lowkey this one gets ignored for non-DMA statistics, so don't come for her, she's just there for the DMA girlies
