✨ iavf_ptp_set_timestamp_mode(9) ✨

Okay bestie, so we're in the Kernel API Manual today and the star of the show is iavf_ptp_set_timestamp_mode — literally the function that tells your device how it's gonna timestamp stuff. Buckle up, it's short but it's cute 🎀

🌸 NAME 🌸

iavf_ptp_set_timestamp_mode — the one that sets the device timestamping mode, no cap 💅

🦋 SYNOPSIS 🦋

int iavf_ptp_set_timestamp_mode (struct iavf_adapter *adapter , struct
       kernel_hwtstamp_config *config );

🌼 ARGUMENTS 🌼

  • adapter — your private adapter structure, the main character of the whole operation 👑
  • config — a pointer to kernel_hwtstamp_config, i.e. the vibe check on what config we're working with

💖 DESCRIPTION 💖

So basically it sets the timestamping mode that got requested from userspace. That's it, that's the function — short, sweet, does exactly what it says on the tin 🍓

⭐ NOTE ⭐

Okay this part is important, don't skip it: this function always translates Rx timestamp requests for any packet category into HWTSTAMP_FILTER_ALL. Like, every single one. Not a drill 😭

🎀 RETURN 🎀

  • 0 on success, slay ✨
  • a negative error code otherwise, and we simply do not stan 💀
