DEVICE REGISTERS IN THE NE PCI DEVICE MMIO BAR(9)

💅 Device registers in the NE PCI device MMIO BAR ✨

okay bestie, welcome to Device regis...ice MMIO BAR(9) — that's the manual name, yes it's got the little ... in the middle, that's just how it is, we don't question it 💖. This page lives in the Kernel API Manual and it's basically the friend who knows everyone at the party: it doesn't do much talking itself, it just introduces you to literally every other NE PCI page you're gonna need. 🫶

It's giving link hub energy and honestly? iconic. Lowkey the most efficient page in the whole manual. 💅
