User Interface




The packet accelerator (PA) is one of the main components of the network coprocessor (NETCP) peripheral in KeyStone devices. The PA works together with the security accelerator (SA) and the gigabit Ethernet switch subsystem to form a network processing solution. The purpose of PA in the NETCP is to perform packet processing operations such as packet header classification, checksum generation, and multi-queue routing.

Driver Configuration

The driver configures the PASS subsystem using Pa_config_t structure. This structure must be initialized before the Pa_create() function is called and cannot be changed afterwards. Also, there are bunch of system/global configurations and per entry configurations for PA. For details about individual fields of this structure and other configuration API structures, see the Doxygen help by opening PDK_INSTALL_DIR\packages\ti\drv\PA\docs\doxygen\html\index.html.
