Struct driver_virtio::VirtIoNetDev

pub struct VirtIoNetDev<'a, 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<'a, H: Hal, T: Transport, const QS: usize> VirtIoNetDev<'a, H, T, QS>

pub fn try_new(transport: T, irq_num: Option<usize>) -> DevResult<Self>

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

Trait Implementations

impl<H: Hal, T: Transport, const QS: usize> BaseDriverOps for VirtIoNetDev<'_, H, T, QS>

fn device_name(&self) -> &str

The name of the device.

fn device_type(&self) -> DeviceType

The type of the device.

fn get_irq_num(&self) -> Option<usize>

Get the interrupt number. Only interrupt drivers need to implement this function.

fn ack_interrupt(&mut self) -> bool

Ack the interrupt. Only interrupt drivers need to implement this function.

impl<'a, H: Hal, T: Transport, const QS: usize> NetDriverOps<'a> for VirtIoNetDev<'a, 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 fill_rx_buffers(&mut self, buf_pool: &'a NetBufferPool) -> DevResult

Fills the receive queue with buffers.

fn prepare_tx_buffer( &self, tx_buf: &mut NetBuffer<'_>, pkt_len: usize ) -> DevResult

Prepares a buffer for transmitting.

fn recycle_rx_buffer(&mut self, rx_buf: NetBufferBox<'a>) -> DevResult

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

fn transmit(&mut self, tx_buf: &NetBuffer<'_>) -> DevResult

Transmits a packet in the buffer to the network, and blocks until the request completed.

fn receive(&mut self) -> DevResult<NetBufferBox<'a>>

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