igb_phy_sw_reset(9)

💅 igb_phy_sw_reset — from the Kernel API Manual, bestie ✨

Okay so like, quick vibe check: this page lives in the Kernel API Manual, and it's all about igb_phy_sw_reset — yes that's the function, yes we're gonna get into it 🫶

🌸 NAME 🌸

igb_phy_sw_reset — PHY software reset, aka the little "have you tried turning it off and on again" moment for your PHY 💫

---

✨ SYNOPSIS ✨

s32 igb_phy_sw_reset (struct e1000_hw *hw );

Like, that's the whole signature. Short, sweet, iconic 👑

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 💖 that's it, that's the whole argument, she's low maintenance

---

🦋 DESCRIPTION 🦋

So what does she do? Our girl does a software reset of the PHY by reading the PHY control register and then setting/write the control register reset bit to the PHY. That's the entire plot. Main character behaviour, no notes 🔥
