batadv_frag_size_limit(9)

🌸 batadv_frag_size_limit(9) — like, the kernel API manual bestie 💅

okay so first things first, this page lives in the Kernel API Manual and it's all about one lil function called batadv_frag_size_limit. no cap, it's a whole vibe.

---

✨ NAME ✨

batadv_frag_size_limit — literally tells you the maximum possible size of packet to be fragmented. that's it. that's the whole job. iconic behavior honestly 🎀

---

🦋 SYNOPSIS 🦋

size_t batadv_frag_size_limit (void );

she takes nothing, she returns a size_t. main character energy fr fr ⭐

---

💖 ARGUMENTS 💖

• void — no arguments. none. zero. the void is voiding 🙈

like, you don't pass her anything, she doesn't want anything, she's independent 💅

---

🔥 RETURN 🔥

the maximum size of payload that can be fragmented. that's the answer she hands back to you, and it's a size_t, so it's a nice chunky unsigned number. slay 💜

🌈 SEE ALSO 🌈

bestie you GOTTA check out the kernel file that this whole thing lives in, it's literally in ./net/batman-adv/fragmentation.c — go read it, iykyk 👑

and then the whole friend group of frag functions, all of them, no skips:

• batadv_frag_clear_chain(9)
• batadv_frag_purge_orig(9)
• batadv_frag_init_chain(9)
• batadv_frag_insert_packet(9)
• batadv_frag_merge_packets(9)
• batadv_skb_is_frag(9)
• batadv_frag_skb_buffer(9)
• batadv_frag_skb_fwd(9)
• batadv_frag_create(9)
• batadv_frag_send_packet(9)

💀 real talk: they're all listed in the same SEE ALSO blob as the kernel file ./net/batman-adv/fragmentation.c, so if you're out here reading this page you're lowkey also being told to go read all of those. do with that what you will 🫶

and that's the whole page!! 🍓 this cutie came out of ./net/batman-adv, dated October 2026, and if you ever need to find her again just look up batadv_frag_size_limit(9). mwah 💖✨🧚
