Struct mlx5::ConnectX5Nic

pub struct ConnectX5Nic { /* private fields */ }

Struct representing a ConnectX-5 network interface card.

Implementations

impl ConnectX5Nic

Functions that setup the NIC struct and transmit packets.

pub fn init( mlx5_pci_dev: &PciDevice, num_tx_descs: usize, num_rx_descs: usize, mtu: u16 ) -> Result<&'static IrqSafeMutex<ConnectX5Nic>, &'static str>

Initializes the new ConnectX-5 network interface card that is connected as the given PciDevice. (steps taken from the PRM, Section 7.2: HCA Driver Start-up)

Arguments

• mlx5_pci_dev: Contains the pci device information for this NIC.
• num_tx_descs: The number of descriptors in each transmit queue.
• num_rx_descs: The number of descriptors in each receive queue.
• mtu: Maximum Transmission Unit in bytes

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

Returns the MAC address of the physical function

pub fn send(&mut self, buffer: TransmitBuffer) -> Result<(), &'static str>

Adds a packet to be sent to the transmit queue and returns once it is sent.

pub fn send_fastpath(&mut self, buffer_addr: PhysicalAddress, buffer: &[u8])

Adds a packet to be sent to the transmit queue.
