igc_force_speed_duplex(9)

💖 NAME 💖

Okay so this is the Kernel API Manual page for igc_force_speed_duplex(9), and she is lowkey iconic. 💅

igc_force_speed_duplex — force PHY speed and duplex settings. Periodt. 🎀

🌸 SYNOPSIS 🌸

s32 igc_force_speed_duplex (struct igc_hw *hw );

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure. That's the whole argument, bestie — just a pointer to the HW structure, carrying the whole vibe. 🫶

🧚 DESCRIPTION 🧚

Okay so what this icon does: it programs the GPY PHY control register to disable autonegotiation and force the speed/duplex indicated by hw->mac.forced_speed_duplex. No cap, that's literally the move. ✨
