Struct mlx_ethernet::work_queue::WorkQueueEntrySend

#[repr(C)]
pub struct WorkQueueEntrySend { /* private fields */ }

WQEs are built from multiple segments. In the case of Send WQEs, there are three:

• control segment
• eth segment
• memory pointer data segment

Implementations

impl WorkQueueEntrySend

pub fn init(&mut self)

set a WQE to an initial state

pub fn send( &mut self, wqe_index: u32, sqn: u32, lkey: u32, local_address: PhysicalAddress, packet: &[u8] )

Fill the control, ethernet and data segments of the WQE to send packets.

Arguments

• wqe_index: WQEBB number of the first block of this WQE // TODO? seems to be wqe_counter
• sqn: number of the SQ this WQE is posted to
• lkey: the lkey used by the SQ
• local_address: physical address of the packet buffer
• packet: packet buffer

pub fn nop(&mut self, wqe_index: u32, sqn: u32)

Fill the control segment of the WQE to execute a NOP.

Arguments

• wqe_index: WQEBB number of the first block of this WQE
• sqn: number of the SQ this WQE is posted to

pub fn dump(&self, i: usize)

Prints out the fields of a WQE in the format used by other drivers (e.g. Linux, Snabb)
