💅 axienet_init_legacy_dma(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for axienet_init_legacy_dma, and we're gonna get you comfy with it, no cap 🫶

---

🌸 NAME 🌸

axienet_init_legacy_dma — init the dma legacy code ✨ (yes that's literally the whole thing, it does what it says, iconic behaviour honestly)

---

🎀 SYNOPSIS 🎀

int axienet_init_legacy_dma (struct net_device *ndev );

like… that's the whole call, that's the vibe 💅

---

🦋 ARGUMENTS 🦋

• ndev — a pointer to the net_device structure, aka the whole personality of your network device, she's the main character here 👑

---

⭐ RETURN ⭐

0 on success 💖 … and a non-zero error value on failure 😭 (so like, always check her, fr fr)

---

🔥 DESCRIPTION 🔥

so bestie, this is the dma initialization code — that's her whole job 💅 She also allocates interrupt service routines, enables the interrupt lines, and handles the ISR handling. lowkey a lot of responsibility for one little function but she ate, honestly 🍓
