Struct IxgbeDevice 

pub struct IxgbeDevice<H: IxgbeHal, const QS: usize> { /* private fields */ }

The main Intel 82599 device driver.

Implementations

impl<H: IxgbeHal, const QS: usize> IxgbeDevice<H, QS>

pub fn init( base: usize, len: usize, num_rx_queues: u16, num_tx_queues: u16, pool: &Arc<MemPool>, ) -> IxgbeResult<Self>

Initializes a new ixgbe device.

This function performs the complete device initialization sequence including:

• Global reset
• Link configuration (auto-negotiation)
• RX/TX queue initialization
• Promiscuous mode enable

Arguments

• base - Physical base address of the device’s MMIO region
• len - Length of the MMIO region
• num_rx_queues - Number of receive queues to initialize
• num_tx_queues - Number of transmit queues to initialize
• pool - Memory pool for packet buffer allocation

Returns

An initialized device ready for packet I/O.

Errors

Returns IxgbeError if:

• DMA allocation fails
• Queue size is invalid
• Memory pool is exhausted

Panics

Panics if num_rx_queues or num_tx_queues exceeds MAX_QUEUES.

pub fn num_rx_queues(&self) -> u16

Returns the number of receive queues configured on this device.

pub fn num_tx_queues(&self) -> u16

Returns the number of transmit queues configured on this device.

Trait Implementations

impl<H: IxgbeHal, const QS: usize> NicDevice<H> for IxgbeDevice<H, QS>

fn get_link_speed(&self) -> u16

Returns the link speed of this device.

fn get_mac_addr(&self) -> [u8; 6]

Returns the mac address of this device.

fn reset_stats(&mut self)

Resets the stats of this device.

fn send(&mut self, queue_id: u16, tx_buf: IxgbeNetBuf) -> IxgbeResult

Sends a network buffer to the network. If currently queue is full, returns an error with type IxgbeError::QueueFull`.

fn can_receive(&self, queue_id: u16) -> IxgbeResult<bool>

Whether can receiver packet.

fn can_send(&self, queue_id: u16) -> IxgbeResult<bool>

Whether can send packet.

fn get_driver_name(&self) -> &str

Returns the driver’s name.

fn recycle_tx_buffers(&mut self, queue_id: u16) -> IxgbeResult

Polls the transmit queue for completed packets and frees their buffers.

fn receive_packets<F>( &mut self, queue_id: u16, packet_nums: usize, f: F, ) -> IxgbeResult<usize>

where F: FnMut(IxgbeNetBuf),

Receives up to packet_nums packets from the network.
