ice_devlink..._hw_addr_get(9)

💅 ice_devlink..._hw_addr_get(9) — like, the Kernel API Manual, bestie 🎀

okay so we're deep in the Kernel API Manual today and honestly? this one is short and sweet and I'm obsessed. it's the devlink handler for getting a mac address, and no cap it just... does the thing. let's go ✨

🌸 NAME 🌸

ice_devlink_port_fn_hw_addr_get — the devlink handler for mac address get, periodt 💅

---

🦋 SYNOPSIS 🦋

int ice_devlink_port_fn_hw_addr_get (struct devlink_port *port , u8
*hw_addr , int *hw_addr_len , struct netlink_ext_ack *extack );

like, four args, returns an int, that's the whole vibe 🫶

---

✨ ARGUMENTS ✨

• port — pointer to devlink port 👑 this is the main character
• hw_addr — hw address to set 🙈 yes bestie the wording says "to set", we are quoting the lore exactly
• hw_addr_len — hw address length 📏
• extack — extack for reporting error messages 😭 so when things go wrong, this is who tells you

---

💖 DESCRIPTION 💖

Returns mac address for the port. that's it. that's the whole description. short king behavior fr fr 🌈

---

⭐ RETURN ⭐

zero on success or an error code on failure — literally the classic. zero means slay, anything else means something went sideways and you should probably look at that extack 👀
