ctucan_do_set_mode(9)

okay so bestie, welcome to the ctucan_do_set_mode(9) page from the Kernel API Manual — it's literally the kernel function that handles setting the driver's mode, and we're gonna get into it 💅✨

✨ NAME ✨

ctucan_do_set_mode — sets the mode of the driver. That's the whole function-name vibe: it sets modes, periodt 🎀

🦋 SYNOPSIS 🦋

Here's the signature, untouched, because we do not mess with signatures:

int ctucan_do_set_mode (struct net_device *ndev , enum can_mode mode );

🌸 ARGUMENTS 🌸

• ndev — a pointer to the net_device structure. That's the device's main character energy right there 🫶
• mode — tells the mode of the driver. That's the mode info going in, no cap.

🧚 DESCRIPTION 🧚

This checks the driver's state and calls the corresponding modes to set. So it's like: vibe check the driver's state, then call the corresponding modes to set. Lowkey straightforward, highkey important 🔥

🌈 RETURN 🌈

Returns 0 on success, and a failure value on error. So 0 is the slay outcome; anything else means error city, bestie 😭
