batadv_mcas...s_bridge_get(9)

💅 batadv_mcast_mla_rtr_flags_bridge_get(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this one's a kernel function page, so grab your iced coffee and let's get into it 🫶

---

🌸 NAME 🌸

batadv_mcast_mla_rtr_flags_bridge_get — literally just getting the mcast router flags from the bridge 🎀

---

✨ SYNOPSIS ✨

u8 batadv_mcast_mla_rtr_flags_bridge_get (struct batadv_priv *bat_priv ,
struct net_device *bridge );

---

🦋 ARGUMENTS 🦋

• bat_priv — the bat priv, aka the one holding all the mesh interface information 👑
• bridge — the bridge interface sitting on top of the mesh_iface if there even is one; if not, just pass NULL and vibe 🙈

---

💖 DESCRIPTION 💖

It checks whether there's an IPv4 multicast router and an IPv6 multicast router hanging out behind a bridge. That's the whole assignment. Slay. ✨

---

🌈 RETURN 🌈

• BATADV_NO_FLAGS — both an IPv4 and IPv6 multicast router is present 🎉 (iconic, honestly)
• BATADV_MCAST_WANT_NO_RTR4 — no IPv4 multicast router is present 💀
• BATADV_MCAST_WANT_NO_RTR6 — no IPv6 multicast router is present 😭
• the former two OR'd together — no multicast router is present at all, not a single one, periodt 🌸
