STRUCT BATADV_UNICAST_TVLV_PACKET(9)

💖 NAME 💖

Okay bestie, welcome to the Kernel API Manual page for struct batadv_unicast_tvlv_packet(9) — she’s literally the blueprint for a generic unicast packet with tvlv payload. No cap. 💅

✨ SYNOPSIS ✨

struct batadv_unicast_tvlv_packet {
    __u8 packet_type;
    __u8 version;
    __u8 ttl;
    __u8 reserved;
    __u8 dst[ETH_ALEN];
    __u8 src[ETH_ALEN];
    __be16 tvlv_len;
    __u16 align;
};

🦋 Members 🦋

• packet_type — batman-adv packet type, part of the general header. 🛰️
• version — batman-adv protocol version, part of the general header. 🔢
• ttl — time to live for this packet, part of the general header. ⏳
• reserved — reserved field (for packet alignment). 🧷
• dst — address of the destination. 📬
• src — address of the source. 📮
• tvlv_len — length of tvlv data following the unicast tvlv header. 📏
• align — 2 bytes to align the header to a 4 byte boundary. 🧚
