e1000_set_master_slave_mode(9)

💅 e1000_set_master_slave_mode(9) — like, the whole glow-up

okay so bestie, welcome to the Kernel API Manual ✨ this one's a lil' e1000e PHY function and honestly it's giving "small function, big responsibilities" 🎀

---

🌸 NAME 🌸

e1000_set_master_slave_mode — sets the PHY up for Master/slave mode 🫶 that's it, that's the job, no cap.

---

✨ SYNOPSIS ✨

s32 e1000_set_master_slave_mode (struct e1000_hw *hw );

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure. yeah, the whole hardware struct. she's the main character of this function, fr fr 👑

---

💜 DESCRIPTION 💜

so like, literally what it says on the tin: sets up Master/slave mode 🎀 the PHY gets configured for it, and that's the whole vibe check. short and iconic, periodt.
