🎀 ARGUMENTS 🎀

• peer — the destination peer 🫶 like, who are we even sending this to, bestie? this is them.
• bind — the binding related to the destination peer 🔗 it's the connection-y situation attached to that peer, iykyk.
• cache — dst cache 💾 the destination cache, keeping things speedy so we're not out here doing lookups from scratch every single time 😭
• sk — the socket to send the packet over 🧦 this is the actual udp socket the packet rides out on.
• skb — the packet to send 📨 the literal payload, the main character of this whole operation, no notes 👑
• key — the route key snapshot used for cache validation and flow lookup 🔑⭐ she does double duty: checks that the cache is still valid, and helps with the flow lookup. multi-talented fr fr.
