💅 iptfs_enqueue(9) 💅

okay bestie, listen — this is a page from the Kernel API Manual and honestly it's short but it matters. It's giving "small function, big responsibilities" and I'm obsessed. Let's get into it ✨

🌸 NAME 🌸

iptfs_enqueue — enqueue packet if ok to send. that's it, that's the whole vibe. lowkey a queen of a one-liner 🫶

---

🎀 SYNOPSIS 🎀

bool iptfs_enqueue (struct xfrm_iptfs_data *xtfs , struct sk_buff *skb
);

like, look at her. returns a bool, takes two pointers, no drama. periodt 💅

---

🦋 ARGUMENTS 🦋

• xtfs — the xtfs state. yes babe, the state of the thing. it's carrying the whole situation fr fr 🧚
• skb — the packet. the actual packet. the main character of this whole operation 👑

---

⭐ RETURN ⭐

iykyk: true = it went in. that's literally the whole contract, no cap ✨
