Struct Nic

pub struct Nic {
    pub interface: NetworkInterface,
    /* private fields */
}

NIC Structure that supports Packetvisor

Fields

interface: NetworkInterface

Attached network interface information. (ex. interface name, L2-3 address, etc.)

Implementations

impl Nic

pub fn new( if_name: &str, chunk_size: usize, chunk_count: usize, fq_size: usize, cq_size: usize, tx_size: usize, rx_size: usize, ) -> Result<Nic, String>

Description

Attaching pv::Nic to network interface

Arguments

if_name - network interface name
chunk_size - total size of packet payload
chunk_count - total count of chunk
fq_size - filling ring size
cq_size - completion ring size
tx_size - tx ring size
rx_size - rx ring size \

Returns

On success, returns pv::Nic bound to the network interface.
On failure, returns an error string.

pub fn alloc_packet(&self) -> Option<Packet>

Description

Allocate packet using Pool

Returns

On success, returns pv::Packet with empty payload.
On failure, returns None.

pub fn send(&mut self, packets: &mut Vec<Packet>) -> usize

Description

Send packets
*Sent packets are removed from the vector.

Arguments

packets - Packets to send

Returns

Number of packets sent

pub fn receive(&mut self, len: usize) -> Vec<Packet>

Description

Receive packets

Arguments

len - Number of packets to receive

Returns

Received packets
