STRUCT BATADV_MCAST_MLA_FLAGS(9)

💅 struct batadv_mcast_mla_flags 💅

okay so welcome to the Kernel API Manual, section 9 bestie — today's main character is struct batadv_mcast_mla_flags, and it's literally just a lil bundle of flags holding the querier, bridge and tvlv state together. no cap, it's giving "small struct, big responsibilities" 🎀

---

✨ NAME ✨

struct batadv_mcast_mla_flags — flags for the querier, bridge and tvlv state 🦋

---

🌸 SYNOPSIS 🌸

struct batadv_mcast_mla_flags {
    struct batadv_mcast_querier_state querier_ipv4;
    struct batadv_mcast_querier_state querier_ipv6;
    unsigned char enabled:1;
    unsigned char bridged:1;
    u8 tvlv_flags;
 };

like, look at her. two whole querier state structs, two single-bit flags, and one u8. iconic. 💅

---

👑 Members 👑

• querier_ipv4 — the current state of an IGMP querier in the mesh 🐝 (yes, IGMP, the IPv4 one)
• querier_ipv6 — the current state of an MLD querier in the mesh 🌈 (that's the IPv6 girlie)
• enabled — whether the multicast tvlv is currently enabled ✨ (one bit, :1, living its tiny truth)
• bridged — whether the mesh interface has a bridge on top 🌉 (also :1, also doing the most with very little)
• tvlv_flags — the flags we have last sent in our mcast tvlv 📬 (a u8, so she's got range)

bestie that's a LOT of cross-references and I need you to know I typed every single one. main character energy only. 💀🫶

and that's the whole page!! brought to you straight out of ./net/batman-adv, dated October 2026 — mwah, go read your structs, ily, bye 💖✨🍓
