batadv_dbg_arp(9)

💅 batadv_dbg_arp(9) — the kernel API glow-up

okay so bestie, real talk: this is a kernel API manual page (the 9 section, kernel dev docs, iykyk), and it's all about one little helper that spills the tea on your ARP packets. It's giving "debug print but make it forensic" ✨

---

🌸 NAME

batadv_dbg_arp — prints a debug message that's got all the ARP packet details in it. every single one. no cap 💅

---

✨ SYNOPSIS

void batadv_dbg_arp (struct batadv_priv *bat_priv , struct sk_buff *skb
, int hdr_size , char *msg );

---

🎀 ARGUMENTS

• bat_priv — the bat priv holding all the mesh interface information 🦋 like, the whole vibe of the mesh lives in here
• skb — the ARP packet itself, the main character of this whole operation 👑
• hdr_size — size of whatever header might sit before the ARP packet, so we know where the good stuff starts
• msg — the message you want printed alongside all the debugging info, your little caption on the debug post 🫶
