✨ batadv_frag_skb_buffer(9) ✨

okay so bestie, welcome to the <pink>batadv_frag_skb_buffer</pink> page from the Kernel API Manual — this is the batman-adv fragmentation lore and honestly it's lowkey iconic 💅

---

🌸 NAME 🌸

batadv_frag_skb_buffer — buffer a fragment for later merging, bestie 🎀

---

🦋 SYNOPSIS 🦋

bool batadv_frag_skb_buffer (struct sk_buff **skb , struct
       batadv_orig_node *orig_node_src );

---

💖 ARGUMENTS 💖

• skb — the skb you wanna buffer, periodt 💫
• orig_node_src — the originator that the skb is received from, iykyk 👑

---

🔥 DESCRIPTION 🔥

so the whole vibe here: add the fragment to the buffer, and merge fragments if possible 🫶

and there are three possible outcomes, no cap:

1. Packet is merged — return true and set *skb to the merged packet ✨
2. Packet is buffered — return true and set *skb to NULL 💀
3. Error — return false and free skb 😭

---

👑 RETURN 👑

returns true when the packet is merged or buffered, and false when skb is not used 🌈
