batadv_mcast_forw_mode(9)

🌸 NAME 🌸

okay bestie, welcome to the batadv_mcast_forw_mode(9) page from the Kernel API Manual. This function is literally the check on how to forward a multicast packet — it's giving “forwarding decision, but make it mesh” energy, and that's the whole vibe.

✨ SYNOPSIS ✨

       enum batadv_forw_mode batadv_mcast_forw_mode (struct batadv_priv
       *bat_priv , struct sk_buff *skb , unsigned short vid , int *is_routable
       );

🎀 ARGUMENTS 🎀

• bat_priv — the bat priv with all the mesh interface information, aka the main-character struct holding all the mesh deets.
• skb — the multicast packet to check. Drop the packet you wanna vibe-check right here.
• vid — the vlan identifier. Yep, the VLAN ID, iconic.
• is_routable — stores whether the destination is routable; it's the spot where that answer gets kept.

🔥 RETURN 🔥

You get the forwarding mode back as enum batadv_forw_mode — that's the return value, periodt.
