STRUCT IDPF_PTP_TX_TSTAMP(9)

🌸 struct idpf_ptp_tx_tstamp 🌸

okay so this is the Kernel API Manual page for struct idpf_ptp_tx_tstamp(9) — yes the (9) is the section, it's a kernel API thing, iykyk 💅 this whole page is literally just "what's in the struct and what does each field do", and honestly? she ate. no cap.

✨ NAME ✨

struct idpf_ptp_tx_tstamp — Parameters for Tx timestamping 🫶

like, that's it, that's the vibe. it holds the params for Tx timestamping, periodt.

---

🎀 SYNOPSIS 🎀

struct idpf_ptp_tx_tstamp {
    struct list_head list_member;
    u32 tx_latch_reg_offset_l;
    u32 tx_latch_reg_offset_h;
    struct sk_buff *skb;
    u64 tstamp;
    u32 idx;
 };

look at her. six fields. main character energy 🔥

💖 Members 💖

okay bestie let's go field by field, no skipping, we're doing all of them 💜

• list_member — the list member structure ✨ (she's literally in a list, that's her whole thing)
• tx_latch_reg_offset_l — Tx tstamp latch low register offset 🌸
• tx_latch_reg_offset_h — Tx tstamp latch high register offset 🌸 (yes there's a low AND a high, don't @ me, that's just how the registers are)
• skb — the pointer to the SKB for this timestamp request 🦋 like the actual packet that's getting its moment
• tstamp — the Tx tstamp value ⭐ the actual timestamp, the whole point, iconic
• idx — the index of the Tx tstamp 🎀 she's numbered, she's tracked, she's indexed

🦋 SEE ALSO 🦋

if you're obsessed with this struct (and why wouldn't you be) you're gonna wanna go read the kernel file ./drivers/net/ethernet/intel/idpf/idpf_ptp.h, and also these siblings right here — all of them, not skipping a single one, bestie 🙈:

• struct idpf_ptp_cmd(9)
• enum idpf_ptp_access(9)
• struct idpf_ptp_secondary_mbx(9)
• enum idpf_ptp_tx_tstamp_state(9)
• struct idpf_ptp_tx_tstamp_status(9)
• struct idpf_ptp_vport_tx_tstamp_caps(9)
• struct idpf_ptp(9)
• idpf_ptp_info_to_adapter(9)
• struct idpf_ptp_dev_timers(9)
• idpf_ptp_is_vport_tx_tstamp_ena(9)
• idpf_ptp_is_vport_rx_tx_tstamp_ena(9) — wait no, hold up, it's idpf_ptp_is_vport_rx_tstamp_ena(9), my bad, don't come for me 😭

there's a whole little family of PTP friends and honestly they're all so valid 👑

ngl this page is short but she's doing exactly what she needs to do — struct, members, references, done. slay. 🍓

and that's the whole page, bestie 💖 quick little sign-off: this one comes from ./drivers/net/ethernet/intel/idpf, dated October 2026, and it's the struct idpf_ptp_tx_tstamp(9) page in all her glory. mwah. 😘🌈🧚
