emac_dev_open(9)

💖 NAME 💖

okay so bestie, this page is emac_dev_open — the EMAC device open page — and it lives in the Kernel API Manual, section 9. Yes, we're in kernel API manual territory, and it's lowkey iconic. 🫶

✨ SYNOPSIS ✨

int emac_dev_open (struct net_device *ndev );

🎀 ARGUMENTS 🎀

• ndev — the DaVinci EMAC network adapter. That's the whole argument, and it's giving main character energy. 💅

🦋 DESCRIPTION 🦋

So emac_dev_open gets called when the system wants to start the interface. During the open, we init the TX/RX channels, enable the hardware for packet reception/transmission, and start the network queue. It's literally the "wake up, network era" moment, no cap. ✨

Returns 0 for a successful open, or the appropriate error code when things are not a slay. Keep that in mind, bestie. 😭
