Field Documentation

ChHandle

Udma_ChHandle Udma_FlowPrms::ChHandle

[IN] TX/RX chHandle.

einfoPresent

uint8_t Udma_FlowPrms::einfoPresent

[IN] Set to 1 if extended packet info is present in the descriptor

psInfoPresent

uint8_t Udma_FlowPrms::psInfoPresent

[IN] Set to 1 if protocol-specific info is present in the descriptor

errorHandling

uint8_t Udma_FlowPrms::errorHandling

[IN] Determines how starvation errors are handled. 0=drop packet, 1=retry

descType

uint8_t Udma_FlowPrms::descType

[IN] Descriptor type

psLocation

uint8_t Udma_FlowPrms::psLocation

[IN] Protocol-specific info location.

sopOffset

uint16_t Udma_FlowPrms::sopOffset

[IN] Start of rx packet data (byte offset from the start of the SOP buffer)

defaultRxCQ

uint16_t Udma_FlowPrms::defaultRxCQ

[IN] Rx destination queue
