IPTFS_DEFAUL...X_QUEUE_SIZE(9)

✨ IPTFS_DEFAULT_MAX_QUEUE_SIZE ✨

okay bestie, welcome to the Kernel API Manual 💅 this one's a teeny tiny little page but she's iconic in her own way — it's all about IPTFS_DEFAULT_MAX_QUEUE_SIZE, so let's get into it 🫶

---

🌸 NAME 🌸

IPTFS_DEFAULT_MAX_QUEUE_SIZE — the default max output queue size, periodt 💖

---

🦋 SYNOPSIS 🦋

IPTFS_DEFAULT_MAX_QUEUE_SIZE

literally just the thing itself, no arguments, no drama ✨

---

🎀 DESCRIPTION 🎀

so this is the default IPTFS max output queue size, measured in octets 🍓 and like… what even is the output queue? okay so picture this: packets come in, they're destined to go out over an IPTFS tunnel, and they get stored in the output queue first — hanging out there before they're output over the IPTFS tunnel in aggregated/fragmented form. that's the whole vibe 💫

Default is 1M. yes bestie, one meg. she's generous 👑
