batadv_forw_bcast_packet(9)

💖 batadv_forw_bcast_packet(9) 💖

okay so bestie, this is a page from the Kernel API Manual and it's literally all about batadv_forw_bcast_packet — the function that forwards and queues a broadcast packet. yes, that one. let's get into it 🫶

---

✨ NAME ✨

batadv_forw_bcast_packet — forward and queue a broadcast packet 💌

---

🌸 SYNOPSIS 🌸

int batadv_forw_bcast_packet (struct batadv_priv *bat_priv , struct
       sk_buff *skb , unsigned long delay , bool own_packet );

no cap, that's the whole signature. four args, one int coming back atcha.

---

🎀 ARGUMENTS 🎀

• bat_priv — the bat priv, bestie 💅 like, the one holding all the mesh interface information. it's giving main character energy, everything lives in here.
• skb — the broadcast packet you're adding. the actual payload moment ✨
• delay — number of jiffies to wait before sending. yes, jiffies. not seconds, not vibes. lowkey important.
• own_packet — true if it's a self-generated broadcast packet 🙈 like, did you make this? be honest.

---

🦋 DESCRIPTION 🦋

so here's the tea ☕ — this thing transmits a broadcast packet either immediately, or, if a delay is given, after that delay. the way it just decides based on whether you passed a delay? iconic.

and that's not even all of it — it also queues additional retransmissions on wireless interfaces. so it's out here sending and setting up future sends at the same time. multi-tasking queen 👑

---

⭐ RETURN ⭐

• NETDEV_TX_OK on success — slay, we transmitted 💖
• NETDEV_TX_BUSY on errors — not slay, something's off 😭

no in-between, periodt.
