#include <enet_udma.h>
Param struct for the TX channel open function.
The configuration structure for the TX channel open function # EnetDma_openTxCh().
EnetUdma_AutoReclaimPrms EnetUdma_OpenTxChPrms_s::autoReclaimPrms |
Buffer auto-reclaim params
void* EnetUdma_OpenTxChPrms_s::cbArg |
Argument to be used for the callback routines (it should mean something to layer into which the callback calls)
uint32_t EnetUdma_OpenTxChPrms_s::chNum |
UDMA channel to number allocated for transmit. Set to #UDMA_DMA_CH_ANY if the channel to allocate and open could be any from the free pool
bool EnetUdma_OpenTxChPrms_s::disableCacheOpsFlag |
Flag to disable cache operations on the ring memory
EnetUdma_AllocDmaDescFxn EnetUdma_OpenTxChPrms_s::dmaDescAllocFxn |
DMA HPD (host packet descriptor) memory allocation callback
EnetUdma_FreeDmaDescFxn EnetUdma_OpenTxChPrms_s::dmaDescFreeFxn |
Transmit HPD (host packet descriptor) memory free callback
Udma_DrvHandle EnetUdma_OpenTxChPrms_s::hUdmaDrv |
UDMA driver handle
EnetUdma_PktNotifyCb EnetUdma_OpenTxChPrms_s::notifyCb |
Enet UDMA event callback function - this function will be called when the registered packets are transmitted on TX channel
uint32_t EnetUdma_OpenTxChPrms_s::numTxPkts |
Maximum number of transmit packets, used for allocating number of DMA descriptors Note - The HW ring element count field is 19-bit
EnetUdma_AllocRingMemFxn EnetUdma_OpenTxChPrms_s::ringMemAllocFxn |
Callback functions. Callback function typedefs so that the CpswDma layer can call into the app layer and let it translate between the hardware buffer descriptors and packets and the stack/translation layer's buffers and packets
Ring memory allocation callback, this cannot be NULL
EnetUdma_FreeRingMemFxn EnetUdma_OpenTxChPrms_s::ringMemFreeFxn |
Ring memory free function callback, used in close flow
EnetUdma_UdmaChPrms EnetUdma_OpenTxChPrms_s::udmaChPrms |
UDMA channel params
EnetUdma_UdmaChTxPrms EnetUdma_OpenTxChPrms_s::udmaTxChPrms |
UDMA transmit channel params
bool EnetUdma_OpenTxChPrms_s::useProxy |
Flag to indicate if a dedicated proxy should be allocated for the "FQ" for this flow. This should be enabled only for those flows that require very high throughput as there are limited proxy available in the system
