✨ axienet_open(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 — this is the page for axienet_open(9), and honestly it's giving "first day of school energy" for a network driver. let's get into it 🎀

---

🌸 NAME 🌸

axienet_open — the driver open routine. yep, that's the whole vibe. it's the one that shows up and gets everything started. 👑

---

🦋 SYNOPSIS 🦋

int axienet_open (struct net_device *ndev );

---

💜 ARGUMENTS 💜

• ndev — pointer to a struct net_device structure. that's your net device bestie, the whole main character of this function 🫶

---

🌈 RETURN 🌈

• 0 on success. slay. ✨
• a non-zero error value on failure 😭 — so like, if you get not-zero back, something went sideways, no cap.

---

🔥 DESCRIPTION 🔥

so this is the driver open routine, periodt. here's the lil to-do list it runs through:

• it calls phylink_start to start the PHY device — gotta wake the PHY up before anything else happens 💅
• it also allocates interrupt service routines, enables the interrupt lines and ISR handling 🧚
• the Axi Ethernet core gets reset through the Axi DMA core 🔁
• and the buffer descriptors get initialized ⭐

that's it, that's the whole glow-up sequence. one function, four jobs, all iconic 👑
