💅 ixgbe_lpbthresh(9) 💅

okok so this is a page from the Kernel API Manual — yes, that's the manual name, we're doing kernel internals today bestie, put your hair up 🎀

---

✨ NAME ✨

ixgbe_lpbthresh — calculate low water mark for flow control 🚰✨

---

🌸 SYNOPSIS 🌸

int ixgbe_lpbthresh (struct ixgbe_adapter *adapter , int pb );

that's it. that's the whole vibe. one function, two args, she's iconic 💅

---

🦋 ARGUMENTS 🦋

• adapter — the board private structure you're calculating for 🫶 like, the whole adapter's private little world, and you're doing math on it
• pb — the packet buffer you're calculating, fr fr. this is the number that goes in 🧮

💀 reminder bestie: this is a kernel API page. no options, no flags, no exit codes, no env vars — just one function and her 118 closest friends. if you were waiting for an OPTIONS section, she's not coming 🫶

and that's the whole page bestie, go calculate that low water mark for flow control 💖 this came out of ./drivers/net/ethernet/intel/i... with a date of October 2026, so mark your calendar, mwah 💅✨🎀
