sw_set_addr(9)

💖 sw_set_addr(9) 💖

okay bestie, welcome to the Kernel API Manual corner 💅 this one is called sw_set_addr(9), and it's giving tiny-but-important switch energy. no cap.

---

✨ NAME ✨

sw_set_addr — configure switch MAC address 🎀

---

🌸 SYNOPSIS 🌸

void sw_set_addr (struct ksz_hw *hw , u8 *mac_addr );

---

🎀 ARGUMENTS 🎀

• hw — the hardware instance. like, the actual hardware object you're working with, bestie 🫶
• mac_addr — the MAC address. the one and only address getting configured ✨

---

🦋 DESCRIPTION 🦋

real talk: this function configures the MAC address of the switch. that's the whole vibe. it's a void function, so it doesn't hand you back a value — it just does the MAC-address configuring thing 💖
