STRUCT EFX_PTP_EVENT_RX(9)

💖 struct efx_ptp_event_rx(9) 💖

okay so this is a page straight out of the Kernel API Manual, and it's about one little struct — but bestie, it's kind of a big deal. buckle up 🎀

---

✨ NAME ✨

struct efx_ptp_event_rx — a PTP receive event (from MC) 👑

like, it's literally the lil container that holds a PTP event that came in on the receive side, handed over from the MC. no cap.

---

✨ SYNOPSIS ✨

struct efx_ptp_event_rx {
    struct list_head link;
    u32 seq0;
    u32 seq1;
    ktime_t hwtimestamp;
    unsigned long expiry;
};

look at her. five fields. flawless. 💅

---

✨ Members ✨

• link — the list of events. it's how she chains up with all the other events 🦋
• seq0 — first part of the (PTP) UUID 🌸
• seq1 — second part of the (PTP) UUID and the sequence number. two-for-one, she's efficient 💀
• hwtimestamp — the event timestamp ⏰ (hardware said what it said)
• expiry — the time which the packet arrived 🕐

ngl, seq1 doing double duty is giving main character energy — UUID chunk and sequence number in one field. iconic.
