t4_set_hw_addr(9)

💖 NAME 💖

okay so welcome to the t4_set_hw_addr(9) page in the Kernel API Manual, bestie. The name is literally the whole vibe: t4_set_hw_addr - store a port's MAC address in SW. That's it, that's the mission. 🫶

✨ SYNOPSIS ✨

void t4_set_hw_addr (struct adapter *adapter , int port_idx , u8 hw_addr[] );

🎀 ARGUMENTS 🎀

• adapter — the adapter. like, the adapter itself, no extra lore.
• port_idx — the port index. which port we're talking about, bestie.
• hw_addr — the Ethernet address. the address going in.

🌸 DESCRIPTION 🌸

Store the Ethernet address of the given port in SW. 💅

The common code calls this when it retrieves a port's Ethernet address from EEPROM. So EEPROM gives up the address, and this function is where it gets stashed in SW. no cap. ✨
