batadv_send_...via_tt_4addr(9)

💅 batadv_send_skb_via_tt_4addr — the kernel API manual, but make it make sense 💅

okay so bestie, this is batadv_send_skb_via_tt_4addr(9) from section 9 of the Kernel API Manual — like, the batman-adv girlies' very own corner of the kernel docs 🦋. She's a send function, she's a lookup function, she's literally both. Let's get into it ✨

✨ NAME ✨

batadv_send_skb_via_tt_4addr — send an skb via TT lookup 🎀

🫶 SYNOPSIS 🫶

int batadv_send_skb_via_tt_4addr (struct batadv_priv *bat_priv , struct
sk_buff *skb , int packet_subtype , u8 *dst_hint , unsigned short vid );

🌸 ARGUMENTS 🌸

• bat_priv — the bat priv with all the mesh interface information 💖 like, she contains multitudes, she holds the whole mesh's business
• skb — the payload to send 📦 your little data baby, off she goes
• packet_subtype — the unicast 4addr packet subtype to use 🎯 you pick which flavor of unicast-4addr she's gonna be
• dst_hint — can be used to override the destination contained in the skb 👀 yeah, you can be shady and redirect her, no cap
• vid — the vid to be used to search the translation table 🔎 this is the key for the TT lookup, iykyk

👑 DESCRIPTION 👑

okay so here's the vibe check: first you look up the recipient node for the destination address in the ethernet header — via the translation table, obviously 💅 — then you wrap the given skb into a batman-adv unicast-4addr header 🎁, and then you send this frame to the according destination node. that's it. that's the whole arc. main character energy from start to finish ⭐

🔥 RETURN 🔥

NET_XMIT_DROP in case of error 😭 or NET_XMIT_SUCCESS otherwise ✨ slay

okay that's the whole page, 100% ate, no crumbs left 🧚. this lil gem lives in ./net/batman-adv and the docs are dated October 2026 — and yes, she's still filed as batadv_send_...via_tt_4addr(9), the truncated-name girlboss herself 👑💜 bye bestie, go send some skbs 💖
