💖 ptp_parse_header(9) 💖

okay bestie, welcome to the Kernel API Manual corner where we talk about ptp_parse_header — she gets you a pointer to the PTP v2 header, and honestly? iconic. 🎀 Every fact is staying right here, no cap.

✨ NAME ✨

ptp_parse_header — Get pointer to the PTP v2 header 🫶

🌸 SYNOPSIS 🌸

struct ptp_header * ptp_parse_header (struct sk_buff *skb , unsigned int
       type );

🎀 ARGUMENTS 🎀

• skb — packet buffer 📦
• type — type of the packet (see ptp_classify_raw) 🔍

🦋 DESCRIPTION 🦋

okay so this function is out here taking care of the VLAN, UDP, IPv4 and IPv6 headers, and the length is checked. 💅 she's doing the absolute most so you don't have to.

🚨 note bestie: internally skb_mac_header is used. make sure that the skb is initialized accordingly — no vibes-only setup here, she needs it done right. 🙈

Pointer to the ptp v2 header or NULL if not found. so yeah: found it? pointer. not found? NULL. 😭
