idpf_ptp_ge...tstamps_caps(9)

💖 idpf_ptp_get_vport_tstamps_caps 💖

okay bestie, so this one's from the Kernel API Manual (yes, the actual kernel docs, we're fancy now ✨) and it's literally just... asking the hardware what timestamp stuff it can do. no biggie. let's get into it 🫶

---

✨ NAME ✨

idpf_ptp_get_vport_tstamps_caps — the function that sends a virtchnl message to grab the timestamp capabilities for a vport 💅

---

🌸 SYNOPSIS 🌸

int idpf_ptp_get_vport_tstamps_caps(struct idpf_vport *vport);

---

🎀 ARGUMENTS 🎀

• vport — the virtual port structure. yeah. that's the whole argument list. she's low maintenance 💖

---

🦋 DESCRIPTION 🦋

So basically what happens is: this function sends the virtchnl get vport tstamps caps message, and what comes back is the set of tstamp capabilities for that specific vport. like, per-vport. each one gets its own. no sharing, no cap 🧚

that's it. that's the whole description. iconic brevity honestly 👑

---

⭐ RETURN ⭐

• 0 on success — slay, we love a clean zero 💚
• -errno otherwise — not slay, something went sideways, and the error code comes back negative as is the convention 😭

ngl if you're messing with timestamps on intel idpf NICs, you're gonna be seeing a lot of these idpf_ptp_* functions. consider this your new group chat 💀💜
