✨ NAME ✨

vti6_xmit — send a packet 🦋

like. that's it. that's the whole vibe. it sends a packet.

---

🌸 SYNOPSIS 🌸

int vti6_xmit (struct sk_buff *skb , struct net_device *dev , struct flowi *fl );

so you call it and it hands you back an int, and it takes these three gorgeous little parameters: a struct sk_buff *skb, a struct net_device *dev, and a struct flowi *fl 💅

🎀 ARGUMENTS 🎀

• skb — the outgoing socket buffer, aka the actual packet that's about to go out into the world ✨ lowkey the main character here.
• dev — the outgoing tunnel device, like the tunnel it's travelling through 🫶
• fl — the flow informations for the xfrm_lookup, which is exactly as technical as it sounds, iykyk 💜
