Struct PortConfig 

pub struct PortConfig {
    pub nb_rx_queues: u16,
    pub nb_tx_queues: u16,
    pub nb_rx_desc: u16,
    pub nb_tx_desc: u16,

}

Configuration for an Ethernet port

Fields

nb_rx_queues: u16

Number of RX queues

nb_tx_queues: u16

Number of TX queues

nb_rx_desc: u16

Number of RX descriptors per queue

nb_tx_desc: u16

Number of TX descriptors per queue

promiscuous: bool

Enable promiscuous mode

mtu: u32

MTU size (0 for default)

rx_offload: RxOffload

RX hardware offload configuration

tx_offload: TxOffload

TX hardware offload configuration

Implementations

impl PortConfig

pub fn new() -> Self

Create a new PortConfig with default values

pub fn with_queues(self, rx: u16, tx: u16) -> Self

Set the number of RX/TX queues

pub fn with_descriptors(self, rx: u16, tx: u16) -> Self

Set the number of RX/TX descriptors

pub fn with_promiscuous(self, enable: bool) -> Self

Enable or disable promiscuous mode

pub fn with_mtu(self, mtu: u32) -> Self

Set the MTU

pub fn with_rx_offload(self, offload: RxOffload) -> Self

Configure RX hardware offloads

pub fn with_tx_offload(self, offload: TxOffload) -> Self

Configure TX hardware offloads

pub fn with_checksum_offload(self) -> Self

Enable all checksum offloads (RX and TX)

pub fn with_vlan_offload(self) -> Self

Enable hardware VLAN offloads (RX strip + TX insert).

When the NIC supports it, VLAN tags are stripped on RX (TCI stored in mbuf.vlan_tci) and inserted on TX (from mbuf.vlan_tci). Falls back to software tag handling if the NIC doesn’t support it.

Trait Implementations

impl Clone for PortConfig

fn clone(&self) -> PortConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PortConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PortConfig

fn default() -> Self

Returns the “default value” for a type.
