💅 dev_change_proto_down(9)

okay bestie, welcome to the Kernel API Manual — today's main character is dev_change_proto_down, and no, the name isn't as scary as it looks 🫶

✨ NAME ✨

dev_change_proto_down — sets the carrier according to proto_down, literally that's the whole gig 💖

✨ SYNOPSIS ✨

int dev_change_proto_down (struct net_device *dev , bool proto_down );

✨ ARGUMENTS ✨

• dev — the device 👑 like, the net device you're doing this to
• proto_down — the new value 🎀 yep, that's it, just the new value

✨ RETURN ✨

0 on success, and -errno on failure 😭 (so like, if it doesn't slay, you get a negative errno back, ok?)
