gether_set_dev_addr(9)

🌸 gether_set_dev_addr — it's in the Kernel API Manual, bestie 💅

okay so this is a kernel function page from the Kernel API Manual, and it's literally about giving an ethernet-over-usb link its eth address. iconic behavior, truly. ✨

🎀 NAME 🎀

gether_set_dev_addr — initialize an ethernet-over-usb link with eth address

🦋 SYNOPSIS 🦋

int gether_set_dev_addr (struct net_device *net , const char *dev_addr );

✨ ARGUMENTS ✨

• net — the device that's representing this link 🫶
• dev_addr — the eth address of this device 💖

💜 DESCRIPTION 💜

so here's the tea: this sets the device-side Ethernet address of this ethernet-over-usb link — but only if dev_addr is correct. if the new address is incorrect, it returns a negative errno. no cap, that's the whole vibe check. 🙈

lowkey important: a bad address doesn't get fixed for you, it just comes back as a negative errno. so like, check your address, bestie. 😭
