e1000_get_speed_and_duplex(9)

💅 e1000_get_speed_and_duplex(9) — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual page for e1000_get_speed_and_duplex(9). yes that's the whole title, she's long, she's iconic, get comfy 🎀

---

🌸 NAME 🌸

e1000_get_speed_and_duplex —

and that's it. that's the name section. the dash is just… sitting there. no description. she said "my name is enough" and honestly? valid. 👑

---

⭐ SYNOPSIS ⭐

s32 e1000_get_speed_and_duplex (struct e1000_hw *hw , u16 *speed , u16
*duplex );

(it's one function call, the line break is just the terminal being dramatic, don't panic 🫶)

---

🦋 ARGUMENTS 🦋

• hw — the struct holding all the variables that get passed around by the shared code. she's basically the group chat everyone reads from 💬
• speed — speed of the connection, passed in as a pointer 🏎️
• duplex — the duplex setting of the connection, also a pointer, also important 🌈

---

💖 DESCRIPTION 💖

Detects the current speed and duplex settings of the hardware. that's the whole thing. she looks at your NIC and goes "oh you're running like that huh" and reports back 😭✨ literally the vibe check of ethernet link states.

ngl bestie this page is short but she's carrying a LOT of friends in SEE ALSO. go read them, they're all waiting 💀💖

and that's the page!! 🎀 source she came from is ./drivers/net/ethernet/intel/e... (yes it's cut off like that in the footer, the terminal ran out of room, iconic behavior honestly 😭) and she's dated October 2026, footer's got her full name e1000_get_speed_and_duplex(9) stamped on it. mwah, bye bestie 💅✨🦋
