e1000_phy_fo...speed_duplex(9)

✨ NAME ✨

e1000_phy_force_speed_duplex — force link settings 💅

okay so this page is from the Kernel API Manual — that's the manual name, bestie — and the page itself is e1000_phy_fo...speed_duplex(9). The function is e1000_phy_force_speed_duplex, and it's giving "force link settings" main-character energy. obsessed. 🫶

🌸 SYNOPSIS 🌸

s32 e1000_phy_force_speed_duplex (struct e1000_hw *hw );

that's the signature exactly, no edits, no cap. ✨

🎀 ARGUMENTS 🎀

• hw — struct containing variables accessed by shared code. literally the struct with the variables that shared code accesses. 🦋

💜 DESCRIPTION 💜

It forces the PHY speed and duplex settings to hw->forced_speed_duplex. That's the whole plot: PHY speed and duplex get forced to that field. no extra lore, just the assignment. 🔥
