Struct driver_virtio::VirtIoNetDev

pub struct VirtIoNetDev<H: Hal, T: Transport, const QS: usize> { /* private fields */ }

Available on crate feature net only.

The VirtIO network device driver.

QS is the VirtIO queue size.

Implementations

impl<H: Hal, T: Transport, const QS: usize> VirtIoNetDev<H, T, QS>

pub fn try_new(transport: T) -> DevResult<Self>

Creates a new driver instance and initializes the device, or returns an error if any step fails.

Trait Implementations

fn device_name(&self) -> &str

The name of the device.

fn device_type(&self) -> DeviceType

The type of the device.

impl<H: Hal, T: Transport, const QS: usize> NetDriverOps for VirtIoNetDev<H, T, QS>

fn mac_address(&self) -> EthernetAddress

The ethernet address of the NIC.

fn can_transmit(&self) -> bool

Whether can transmit packets.

fn can_receive(&self) -> bool

Whether can receive packets.

fn rx_queue_size(&self) -> usize

Size of the receive queue.

fn tx_queue_size(&self) -> usize

Size of the transmit queue.

fn recycle_rx_buffer(&mut self, rx_buf: NetBufPtr) -> DevResult

Gives back the rx_buf to the receive queue for later receiving.

fn recycle_tx_buffers(&mut self) -> DevResult

Poll the transmit queue and gives back the buffers for previous transmiting. returns DevResult.

fn transmit(&mut self, tx_buf: NetBufPtr) -> DevResult

Transmits a packet in the buffer to the network, without blocking, returns DevResult.

fn receive(&mut self) -> DevResult<NetBufPtr>

Receives a packet from the network and store it in the NetBuf, returns the buffer.

fn alloc_tx_buffer(&mut self, size: usize) -> DevResult<NetBufPtr>

Allocate a memory buffer of a specified size for network transmission, returns DevResult
