STRUCT VIRTCHNL2_PTP_GET_VPORT_TX_TSTAMP_LATCHES(9)

👑 struct virtchnl2_ptp_get_vport_tx_tstamp_latches — Kernel API Manual energy ✨

okay so bestie, welcome to the struct virtchnl2_ptp_get_vport_tx_tstamp_latches(9) page 🎀 this is from the Kernel API Manual and it's lowkey one of the most underrated little structs in the PTP universe, ngl.

---

🌸 NAME 🌸

struct virtchnl2_ptp_get_vport_tx_tstamp_latches — the Tx timestamp latches that are associated with the vport 💅 that's literally it, that's the whole vibe.

---

✨ SYNOPSIS ✨

struct virtchnl2_ptp_get_vport_tx_tstamp_latches {
    __le32 vport_id;
    __le16 num_latches;
    u8 get_devtime_with_txtstmp;
    u8 pad[1];
    __le64 device_time;
    struct virtchnl2_ptp_tx_tstamp_latch tstamp_latches[];
 };

look at her. iconic layout. flexible array member at the end, we love a struct that knows how to grow 🔥

🧚 Members 🧚

• vport_id — the number of the vport that's asking for the timestamp 🫶 (yes, the number, it's __le32, keep it little-endian bestie)
• num_latches — how many latches we're talking about, count 'em
• get_devtime_with_txtstmp — the flag you set when you want the device time bundled along with the Tx timestamp ⭐
• pad — padding for future extensions, it's giving "reserved for the girlies of tomorrow" 💜
• device_time — the device time, but only if get_devtime_with_txtstmp was set in the request 👀 no flag, no time, that's the deal
• tstamp_latches — PTP TX timestamp latch, the whole reason we're here 🌈

---

💖 Description 💖

So here's the tea: the PF/VF sends this message to receive a specified number of timestamps entries 🕐 like, you tell it how many you want, and it hooks you up.

It's associated with VIRTCHNL2_OP_PTP_GET_VPORT_TX_TSTAMP — that's the op that makes it happen, iykyk ✨

💀 real talk: everything above is verbatim from the manpage, so don't come for me if you mistype a name — the names are the names, no cap.

🌷 that's the whole page bestie, mwah 🫶 sourced from ./include/linux/net/intel, dated October 2026, and yeah the header/footer both still say struct virtc...tamp_latches(9) because the manpage generator truncates it and honestly that's just her main character energy at this point 💅✨
