+# Rust simple e1000 device driver (Intel ethernet adapter)
+
+This is for figuring out proper Rust PCI, DMA, network abstraction APIs for NIC drivers.
+
+This driver works on QEMU, howerver nothing else works.
+
+[Rust-for-Linux tree](https://github.com/Rust-for-Linux/linux) doesn't support necessary abstraction APIs (PCI, DMA, network, etc) yet. This driver is tested with [my fork](https://github.com/fujita/linux/tree/rust-e1000). I'll work for upstreaming.
