ice_devlink..._hw_addr_set(9)

okay so bestie, welcome to the ice_devlink..._hw_addr_set(9) page from the Kernel API Manual 💅 this one is short, focused, and honestly it’s giving “tiny function, clear job” energy. ✨

💖 NAME 💖

ice_devlink_port_fn_hw_addr_set — devlink handler for mac address set. That’s the whole vibe: it handles setting the mac address. 🎀

🦋 SYNOPSIS 🦋

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

✨ ARGUMENTS ✨

• port — pointer to devlink port, aka the port we’re doing this for 👑
• hw_addr — hw address to set, the actual address bestie 🫶
• hw_addr_len — hw address length, so we know how long it is 📏
• extack — extack for reporting error messages, the little messenger when things go sideways 😭

🌸 DESCRIPTION 🌸

Sets mac address for the port, verifies arguments and copies address to the subfunction structure. no cap, that’s the whole description — it’s giving “do the thing, check the thing, copy the thing” 💅

🔥 RETURN 🔥

zero on success or an error code on failure. so: happy path = zero, sad path = error code 💀
