ixgbe_read_pe(9)

💅 ixgbe_read_pe — a whole vibe from the Kernel API Manual

okay so bestie, welcome to the ixgbe_read_pe page 💖 this one lives in the Kernel API Manual, and honestly? it's giving "tiny little function with main character energy" because it does exactly one thing and does it ✨

---

🎀 NAME

ixgbe_read_pe — Read register from port expander 🦋

like, that's it. that's the whole job. you show up, you read a register off the port expander, you leave. no cap 💅

---

🌸 SYNOPSIS

int ixgbe_read_pe (struct ixgbe_hw *hw , u8 reg , u8 *value );

literally just three args and a return value, we love a low-maintenance icon 👑

---

🫶 ARGUMENTS

• hw — pointer to hardware structure. this is your hardware bestie, the struct that knows where everything lives ✨
• reg — register number to read. yes girl, tell it which register 🎀
• value — pointer to receive read value. it doesn't return the value itself, it drops it off at this pointer, iykyk 💌

---

⭐ DESCRIPTION

Returns status code 💀 that's the description. that's all of it. she's short, she's sweet, she's a status-code returner and we respect her for it 🙈
