Trait IRxQueue 

pub trait IRxQueue: Send + 'static {
    // Required methods
    fn id(&self) -> usize;
    fn config(&self) -> QueueConfig;
    fn submit(&mut self, bus_addr: u64, len: usize) -> Result<(), NetError>;
    fn reclaim(&mut self) -> Option<(u64, usize)>;
}

Receive queue interface.

A driver creates one or more RX queues via Interface::create_rx_queue and exchanges DMA buffer bus addresses with the caller.

Required Methods

fn id(&self) -> usize

Queue identifier (unique within the device).

fn config(&self) -> QueueConfig

DMA buffer configuration for this queue.

fn submit(&mut self, bus_addr: u64, len: usize) -> Result<(), NetError>

Submit an empty DMA buffer to hardware.

bus_addr must point to a DMA-capable buffer whose total size is len.

fn reclaim(&mut self) -> Option<(u64, usize)>

Reclaim the next completed receive buffer.

Returns the buffer bus address and the received byte count.
