mpc52xx_fec_start(9)

💅 NAME 💅

mpc52xx_fec_start — okay so this is the Kernel API Manual page for mpc52xx_fec_start, and bestie I have to be honest, the NAME line trails off into a dash and then nothing. Literally the void. No little one-liner description. So the whole personality of this page is just the function name itself. Iconic, honestly.

✨ SYNOPSIS ✨

void mpc52xx_fec_start (struct net_device *dev );

Returns void, takes a pointer to a struct net_device called dev. That's the whole vibe check. 🫶

🎀 ARGUMENTS 🎀

• dev — the network device 💖. As in, a pointer to the struct net_device you're waking up. That's the one and only thing you pass in.

🦋 DESCRIPTION 🦋

So here's the tea: this function gets called to start or restart the FEC during a link change. 🌀

And when does a link change happen, you ask? It happens on fifo errors, or when you're switching between half and full duplex. Like, the link is having a moment and mpc52xx_fec_start is the main character who shows up to get the FEC going again. Periodt. 👑

No cap — those are the only two situations listed here: fifo errors and half ↔️ full duplex switches. Don't @ me with anything else, because the page doesn't say anything else 🙈.
