💖 NAME 💖

batadv_dat_forward_data — copy the payload and yeet it to the candidates we picked 💅

---

🎀 SYNOPSIS 🎀

bool batadv_dat_forward_data (struct batadv_priv *bat_priv , struct
       sk_buff *skb , __be32 ip , unsigned short vid , int packet_subtype );

---

🌸 ARGUMENTS 🌸

• bat_priv — the bat priv holding all the mesh interface info 👑
• skb — the payload we're sending out 🫶
• ip — the DHT key, bestie 🔑
• vid — VLAN identifier, periodt
• packet_subtype — which unicast4addr packet subtype to use 💅

---

⭐ DESCRIPTION ⭐

so basically this function copies the skb using pskb_copy, and then it gets sent as a unicast packet to each of the selected candidates. yes, each of them. iconic behaviour honestly 🔥

---

🌈 RETURN 🌈

true if the packet made it to at least one candidate — slay 💖 — and false otherwise 😭
