okay bestie, welcome to the Kernel API Manual entry for ppp_skb_is_compressed_proto — she’s lowkey niche but highkey useful, and we’re gonna get into it. ✨

✨ NAME ✨

ppp_skb_is_compressed_proto — checks if PPP protocol in a skb is compressed. fr fr, that’s the whole assignment. 💅

bool ppp_skb_is_compressed_proto (const struct sk_buff *skb );

---

🦋 ARGUMENTS 🦋

• skb — the skb to check. that’s the one, bestie. 🫶

💖 DESCRIPTION 💖

Check if the PPP protocol field is compressed — specifically, the least significant bit of the most significant octet is 1. 👑

skb->data must point to the PPP protocol header. that’s the vibe check, no cap. ⭐

bestie, this is not a “maybe it works if data points somewhere else” situation — the manual is clear: skb->data must point to the PPP protocol header. 🙈

---

🔥 RETURN 🔥

Whether the PPP protocol field is compressed. that’s it, that’s the return value, and it’s giving exactly what it says on the tin. 💀✨
