STRUCT VIRTCHNL2_PTP_GET_VPORT_TX_TSTAMP_CAPS(9)

🦋 struct virt..._tstamp_caps(9) 🦋

okay bestie, welcome to the Kernel API Manual — this page is all about struct virtchnl2_ptp_get_vport_tx_tstamp_caps, with the header doing its little shortened-name thing as struct virt..._tstamp_caps(9). iykyk. It's giving Tx tstamp entries, and we're gonna read it together. 💖

✨ NAME ✨

struct virtchnl2_ptp_get_vport_tx_tstamp_caps — the structure that defines Tx tstamp entries. periodt.

💫 SYNOPSIS 💫

the whole struct, exactly as it's written:

struct virtchnl2_ptp_get_vport_tx_tstamp_caps {
    __le32 vport_id;
    __le16 num_latches;
    u8 tstamp_ns_lo_bit;
    u8 tstamp_ns_hi_bit;
    u8 pad[8];
    struct virtchnl2_ptp_tx_tstamp_latch_caps tstamp_latches[];
};

🛠 Members 🛠

• vport_id — vport number, simple as that.
• num_latches — total number of latches.
• tstamp_ns_lo_bit — first bit for the nanosecond part of the timestamp.
• tstamp_ns_hi_bit — last bit for the nanosecond part of the timestamp.
• pad — padding for future tstamp granularity extensions. future-proofing iconic.
• tstamp_latches — capabilities of Tx timestamp entries.

💬 Description 💬

PF/VF sends this message to negotiate the Tx timestamp latches for each Vport. That's the whole move. 🫶
