Struct VirtioNetDriver 

pub struct VirtioNetDriver { /* private fields */ }

VirtIO Network Driver

Implementations

impl VirtioNetDriver

pub fn new(mmio_base: usize) -> Result<Self, KernelError>

Create a new VirtIO Network driver

pub fn transmit(&mut self, packet: &[u8]) -> Result<(), KernelError>

Transmit a packet using virtqueue.

Prepends a VirtioNetHeader, copies the frame data into the pre-allocated TX data buffer, and kicks the device.

pub fn receive(&mut self) -> Result<Option<Packet>, KernelError>

Receive a packet using virtqueue.

Checks the used ring for completed RX buffers, copies the received frame data (after stripping the VirtioNetHeader), recycles the descriptor, and returns the packet.

pub fn mac_address(&self) -> MacAddress

Get MAC address
