e1000e_phy_...duplex_setup(9)

🌸 NAME 🌸

Okay bestie, this is the Kernel API Manual page for e1000e_phy_force_speed_duplex_setup(9) — page tag: e1000e_phy_...duplex_setup(9) ✨

The actual name: e1000e_phy_force_speed_duplex_setup — Configure forced PHY speed/duplex 💅

---

💖 SYNOPSIS 💖

void e1000e_phy_force_speed_duplex_setup (struct e1000_hw *hw , u16
       *phy_ctrl );

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure
• phy_ctrl — pointer to current value of MII_BMCR

---

💅 DESCRIPTION 💅

Okay so this function forces speed and duplex on the PHY, and it does that by running through this whole checklist:

1. disable flow control
2. force speed/duplex on the MAC
3. disable auto speed detection
4. disable auto-negotiation
5. configure duplex
6. configure speed
7. configure the collision distance
8. write configuration to CTRL register

💖 Important: The caller must write to the MII_BMCR register for these settings to take effect.
