igb_ptp_hwtstamp_set(9)

💅 igb_ptp_hwtstamp_set 💅

okay so bestie, welcome to the kernel API manual for igb_ptp_hwtstamp_set(9) — yes that's the whole name, yes it's a mouthful, no we're not shortening it. this is the girl whose entire job is setting hardware time stamping config. that's it. that's her whole personality. iconic behavior tbh 🎀

---

✨ NAME ✨

igb_ptp_hwtstamp_set — the function that sets hardware time stamping config 🕰️✨

like literally that's the gig. setting the hardware timestamping configuration. no cap.

---

🌸 SYNOPSIS 🌸

int igb_ptp_hwtstamp_set (struct net_device *netdev , struct
       kernel_hwtstamp_config *config , struct netlink_ext_ack *extack );

ok so it returns an int (we love a return value), and it takes three arguments. three. not two, not four. we stay consistent 💅

---

🦋 ARGUMENTS 🦋

• netdev — the netdev struct. your network device. the main character of the network device world, honestly 🫶
• config — the timestamping configuration structure. this is where the actual timestamping config lives, so like… yes, it's kind of a big deal 🔥
• extack — the netlink extended ack structure, and it's specifically for error reporting. so if things go sideways, this is the girl who tells you about it 😭💀
