batadv_tt_l...esize_to_mtu(9)

✨ batadv_tt_l...esize_to_mtu(9) ✨

okay bestie, we're in the Kernel API Manual today and this one is a whole little batman-adv moment 🦋 yes the mesh networking batman, not the guy — stay with me, it's actually cute.

---

💖 NAME 💖

batadv_tt_local_resize_to_mtu — resizes the local translation table so it fits the maximum packet size that can actually be transported through the mesh 🎀

like, the table needs to fit in the packet. it's giving "pack light or you're not boarding" energy, no cap.

---

🌸 SYNOPSIS 🌸

void batadv_tt_local_resize_to_mtu (struct net_device *mesh_iface );

it returns void, so literally nothing comes back. it just does the thing. icon behavior 💅

---

🎀 ARGUMENTS 🎀

• mesh_iface — the netdev struct of the mesh interface 🫶 that's it, that's the whole argument, we love a low-maintenance function.

---

⭐ DESCRIPTION ⭐

so what does it do? it removes entries older than 'timeout', and also removes entries older than half the timeout, if more entries still need to go 👑

read that again — 'timeout' first, then half timeout as the second pass, because sometimes you gotta be a little more aggressive to make everything fit. it's a whole two-stage glow-down for your translation table 💀✨
