IPTFS_DEFAUL...ORDER_WINDOW(9)

💅 IPTFS_DEFAUL...ORDER_WINDOW(9) 💅

ok so like — hi bestie, welcome to the Kernel API Manual ✨ this one's a short little icon, she's lowkey famous, and honestly she ate 🎀

---

✨ NAME ✨

IPTFS_DEFAULT_REORDER_WINDOW — the default reorder window size, no cap 🦋

---

🌸 SYNOPSIS 🌸

IPTFS_DEFAULT_REORDER_WINDOW

that's it. that's the whole vibe check. literally just the name, main character energy only 💅

---

🔥 DESCRIPTION 🔥

okay so bestie, this is the default IPTFS reorder window size. and what does a reorder window size even do, you ask? 🧚

it dictates the maximum number of IPTFS tunnel packets in a sequence that may arrive out of order — like, how much chaos your tunnel is willing to politely tolerate before it's like "girl, no" 😭

Default is 3. which is, and I quote, (tcp folks suggested) 👑 — so yeah, the TCP girlies came through with the recommendation and the kernel said slay, we'll take it 💖
