STRUCT BATADV_DHCP_OPTION_HEADER(9)

✨ NAME ✨

struct batadv_dhcp_option_header — the BOOTP/DHCP option header, bestie 💅

okay so real talk, this is the section-9 Kernel API manual page for struct batadv_dhcp_option_header, and it is exactly what it says on the tin: the teeny tiny header that sits in front of every DHCP option. tiny but iconic, fr fr 🎀

🦋 SYNOPSIS 🦋

struct batadv_dhcp_option_header {
    __u8 type;
    __u8 len;
 };

look at her. two fields. zero notes. main character energy 👑

🌸 Members 🌸

• type — what kind of option this is. the vibe check of the option, if you will ✨
• len — how long the option is. the size tag, no cap 📏

like I said. the whole group chat. 💀

💖 that's the whole page, babe. two __u8s and a dream.

and yes, before you ask — this came out of ./net/batman-adv, dated October 2026, and I am obsessed with her. go read the source, ily, bye 🧚‍♀️🌈
