es58x_set_mode(9)

💅 es58x_set_mode — like, the Kernel API Manual page for it ✨

Okay bestie, welcome to the Kernel API Manual entry for es58x_set_mode(9) — this is the lil' function that flips your network device into a different mode. It's short, it's iconic, let's go 🫶

---

✨ NAME ✨

es58x_set_mode — change network device mode. That's it. That's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

int es58x_set_mode (struct net_device *netdev , enum can_mode mode );

Literally just hand it a netdev and a mode and it returns an int. Periodt 💅

---

🎀 ARGUMENTS 🎀

• netdev — the CAN network device itself. Your main character. 👑
• mode — either CAN_MODE_START, CAN_MODE_STOP or CAN_MODE_SLEEP. Those three, no cap, that's the whole roster 🌈

---

🦋 DESCRIPTION 🦋

So like, currently this function is only used to stop and restart the channel during a bus off event 😭 (c.f. es58x_rx_err_msg and drivers/net/can/dev.c:can_restart — those are literally the two only callers, iykyk).

That's it. That's the tea. Not me being obsessed with how narrow the scope is 💀

---

⭐ RETURN ⭐

• zero on success 💖
• errno when any error occurs 🙈

---

🔥 SEE ALSO 🔥

The kernel file ./drivers/net/can/usb/etas_es58x/es58x_core.c — that's where the magic lives ✨

Fr fr, if you're only here to stop or restart a channel after a bus off, you're in exactly the right place. Everyone else, go home 💀
