len );

🎀 ARGUMENTS 🎀

• net — the device representing this link, bestie. that's your main character struct 🫶
• dev_addr — the place to store the device's eth address ✨
• len — the length of the dev_addr buffer, so pls don't let it overflow, iykyk 💅

🦋 DESCRIPTION 🦋

so this one gets the device-side Ethernet address of this ethernet-over-usb link. that's the vibe 💖

it returns zero on success, else a negative errno. periodt. no cap.
