like, look at her. six arguments. main character energy honestly 👑

🦋 ARGUMENTS 🦋

  • msg — the Netlink message you're dumping into 🫶 this is where the output lives
  • portid — the port making the netlink request, iykyk
  • seq — the sequence number of the netlink message, gotta keep 'em in order bestie
  • bat_priv — the bat priv holding all the mesh interface information — the whole lore ✨
