xcan_chip_start(9)

💅 xcan_chip_start — a Kernel API Manual moment (that's the xcan_chip_start(9) manual, bestie)

okay so picture this: it's giving "driver wake-up era" and this little function is the whole main character. ✨

---

🌸 NAME

xcan_chip_start — literally the driver's start routine, no cap.

---

🎀 SYNOPSIS

int xcan_chip_start (struct net_device *ndev );

---

🦋 ARGUMENTS

• ndev — a pointer to the net_device structure 💖 that's it, that's the whole input, she's low maintenance.

---

✨ DESCRIPTION

So this is the driver's start routine, fr fr. What she does is look at the State of the CAN device and then put the CAN device into a proper mode based on that. That's the vibe check — state goes in, correct mode comes out, slay. 👑

---

🔥 RETURN

0 on success 💚 and a failure value on error 😭 (yes, it returns a failure value, that's the whole tea, don't come for her).
