igb_get_spe...uplex_copper(9)

💅 igb_get_speed_and_duplex_copper — Kernel API Manual, section 9 🎀

Okay bestie, welcome to the Kernel API Manual — this one's all about igb_get_speed_and_duplex_copper, and no cap, it's lowkey iconic. The header is giving "my name got truncated in the group chat" energy (igb_get_spe...uplex_copper(9) 😭) but we move. Let's get into it.

✨ NAME ✨

igb_get_speed_and_duplex_copper — Retrieve current speed/duplex 💖

---

🦋 SYNOPSIS 🦋

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

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure — the main character struct, fr fr.
• speed — stores the current speed 🏃‍♀️💨
• duplex — stores the current duplex 🔁

---

🌸 DESCRIPTION 🌸

So the way this works: it reads the status register for the current speed/duplex, then stores the current speed and duplex — specifically for copper connections. That's it, that's the whole vibe. Obsessed with the simplicity tbh. ✨
