es58x_can_reset_echo_fifo(9)

💅 es58x_can_reset_echo_fifo — like, the Kernel API Manual page, bestie ✨

okay so this is es58x_can_reset_echo_fifo, straight out of the Kernel API Manual (section 9, obviously, that's the whole vibe). sit down, grab a strawberry drink 🍓, and lemme tell you about this little function.

---

🌸 NAME 🌸

es58x_can_reset_echo_fifo — it resets the echo FIFO. that's it. that's the tweet. 💅

---

✨ SYNOPSIS ✨

void es58x_can_reset_echo_fifo (struct net_device *netdev );

no return value, she just does it. main character energy fr fr.

---

🎀 ARGUMENTS 🎀

• netdev — the CAN network device. that's your networking homegirl right there 🫶

---

🦋 DESCRIPTION 🦋

okay so first thing you need to know: the echo_skb array of struct can_priv gets flushed by drivers/net/can/dev.c:can_flush_echo_skb — that's not this function's job, that's already handled elsewhere, noted, moving on. 💀

what this function does is it resets the parameters of the struct es58x_priv of our device, and it also resets the queue (c.f. BQL — yes bestie, BQL, byte queue limits, iykyk). so like: priv params → reset, queue → reset. both. clean slate. iconic. ✨
