STRUCT IONIC_LIF_SETPHC_CMD(9)

💅 struct ionic_lif_setphc_cmd(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ this is the page for struct ionic_lif_setphc_cmd — literally the vibe check for Set LIF PTP Hardware Clock 🕰️💖

---

🌸 NAME 🌸

struct ionic_lif_setphc_cmd — Set LIF PTP Hardware Clock 🎀

---

✨ SYNOPSIS ✨

here's the whole glow-up, no edits, copy it exactly bestie:

struct ionic_lif_setphc_cmd {
    u8 opcode;
    u8 rsvd1;
    __le16 lif_index;
    u8 rsvd2[4];
    __le64 tick;
    __le64 nsec;
    __le64 frac;
    __le32 mult;
    __le32 shift;
    u8 rsvd3[24];
 };

---

🦋 Members 🦋

okay this is the cast, and every single one of them is a main character in their own way 👑

• opcode — the opcode, periodt. that's its whole job 💅
• rsvd1 — reserved byte(s). not for you, bestie, hands off 🙈
• lif_index — the LIF index 🎀
• rsvd2 — reserved byte(s). also not yours ✨
• tick — the hardware stamp tick of an instant in time ⏱️🔥
• nsec — the nanosecond stamp of that same instant 🧚
• frac — the fractional nanoseconds at that same instant, like the crumbs of time 🍓
• mult — the cycle to nanosecond multiplier ✖️
• shift — the cycle to nanosecond divisor, and it's a power of two (iykyk) 👑
• rsvd3 — reserved byte(s). again, reserved, so like… respect the boundary 💀

ngl bestie, this whole page is about setting a LIF PTP hardware clock, and the reserved fields stay reserved — do not touch, do not rename, do not "improve" 😤💀

okay that's the whole page, mwah 🫶 this came out of the kernel docs under ./drivers/net/ethernet/pensand... and it's dated October 2026 ⭐ go forth and slay, bestie 💖👑🌸
