e1000_get_cfg_done_ich8lan(9)

💖 e1000_get_cfg_done_ich8lan 💖

okay bestie, welcome to the Kernel API Manual page for e1000_get_cfg_done_ich8lan(9) — she’s lowkey a reset-status girlie and honestly? iconic. ✨

---

🌸 NAME 🌸

e1000_get_cfg_done_ich8lan — read the config done bit after a Full reset or a PHY reset. it’s giving “post-reset vibe check” energy, no cap 💅

---

✨ SYNOPSIS ✨

s32 e1000_get_cfg_done_ich8lan (struct e1000_hw *hw );

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure, aka the hardware object she’s working with 🫶

---

🦋 DESCRIPTION 🦋

okay so here’s the tea: she reads the appropriate register for the config done bit to get the completion status, and then configures the PHY through s/w for the EEPROM-less parts. literally doing both jobs, bestie — status check first, PHY setup after. main character energy fr fr 🌈

---

⚠️ NOTE ⚠️

some silicon which is EEPROM-less will fail trying to read the config done bit, so only an error is logged and she continues. that part is important, bestie: no dramatic bail-out. if we were to return with error, EEPROM-less silicon would not be able to be reset or change link. periodt. 💀
