CDI SDK
SDK for transporting chunks of data reliably and with low latency using a polled mode network driver.

Structure used to hold a transmit packet work request. The lifespan of a work request starts when a packet is queued to be sent and ends when a message is received that it has either been successfully sent or a failure has occurred. More...

Data Fields | ||
| TxPayloadState * | payload_state_ptr | |
| Pointer to Tx payload state structure. | ||
| uint16_t | payload_num | |
| Packet payload number. | ||
| uint16_t | packet_payload_size | |
| Size of payload, not including the packet header. | ||
| Packet | packet | |
| The top level packet structure for the data in this work request. | ||
| CdiPoolHandle | header_pool_handle | |
| Handle of pool associated with header pointer in structure below. If non-null then header pointer is valid. If payload_state_ptr->app_payload_cb_data.extra_data_size is non-zero, then extra_header_ptr is used, otherwise header_ptr is used. | ||
| union { | ||
| void * union_ptr | ||
| TxPacketHeader * header_ptr | ||
| Pointer to data for the packet header. It uses entry zero in the packet SGL. NOTE: Must point to a buffer in the DMA TX memory region that is allocated during adapter initialization. | ||
| TxExtraPacketHeader * extra_header_ptr | ||
| Pointer to data for the packet header that contains extra data. It uses entry zero in the packet SGL. NOTE: Must point to a buffer in the DMA TX memory region that is allocated during adapter initialization. | ||
