Field Documentation

◆ txInterruptPerMSec

uint32_t EnetCpdma_Cfg::txInterruptPerMSec

Number of tx Interrupts per millisecond

◆ rxInterruptPerMSec

uint32_t EnetCpdma_Cfg::rxInterruptPerMSec

Number of rx Interrupts per millisecond

◆ enChOverrideFlag

bool EnetCpdma_Cfg::enChOverrideFlag

Flag to enable channel override feature to be used by classifier. For Rx channels, the packet is directed to a specific rx channel number based on switch priority by default. The default priority mapping is identity based like packet with priority 1 will go to rx channel 1, and so on. To override this and direct packets to a specific rx channels based on ALE flow id classifier match enable this flag. This feature is supported only on AM263x SOC and not AM273x/AWR294x

◆ enHostRxTsFlag

bool EnetCpdma_Cfg::enHostRxTsFlag

Flag to enable timestamp encapsulated packet.

◆ rxChInitPrms

EnetCpdma_RxChInitPrms EnetCpdma_Cfg::rxChInitPrms

RX channel configuration parameters

◆ maxTxChannels

uint32_t EnetCpdma_Cfg::maxTxChannels

Maximum number of Tx channels. Must be <= ENET_CPDMA_CPSW_MAX_TX_CH

◆ maxRxChannels

uint32_t EnetCpdma_Cfg::maxRxChannels

Maximum number of Rx channels. Must be <= ENET_CPDMA_CPSW_MAX_RX_CH
