💅 batadv_is_ap_isolated(9) — check if a packet from the upper layer should get dropped

okay bestie, welcome to the Kernel API Manual ✨ this one's a tiny little function with a big job, and honestly? it's giving gatekeeper energy 💅

---

🌸 NAME 🌸

batadv_is_ap_isolated — check if packet from upper layer should be dropped

like, that's literally the whole thing 😭 it peeks at a packet and decides if it should get dropped. no cap.

---

🦋 SYNOPSIS 🦋

bool batadv_is_ap_isolated (struct batadv_priv *bat_priv , u8 *src , u8
*dst , unsigned short vid );

it returns a bool, bestie. question mark energy. 🔥

---

🎀 ARGUMENTS 🎀

• bat_priv — the bat priv with all the mesh interface information ✨ this is the main character, it's holding all the tea 🫖
• src — source mac address of packet 👑
• dst — destination mac address of packet 🌈
• vid — vlan id of packet 🦋

---

⭐ RETURN ⭐

true when src+dst(+vid) pair should be isolated, false otherwise 💀 that's it. that's the answer. no in-between, no "it depends", just vibes and a boolean 🙈

fr fr, this is the whole decision: isolated or not isolated. the packet gets the ✨treatment✨ or it doesn't.

bestie note: _batadv_is_ap_isolated(9) is right there in the list and it is not the same name as this page — the underscore is doing work, don't @ me 🙈
