The Netronome's Network Flow Processor chip is highly programmable with the goal of processing packets at high speed. Processing units and other chip components are available from the host through the PCIe CPP(Command Push Pull bus) interface. The NFP PF PMD configures a CPP handler for setting up and working with vNICs, perform actions like link up or down, or accessing extended stats from the MAC component. There exist NFP host tools which access the NFP components for programming and debugging but they require the CPP interface. When the PMD is bound to the PF, the DPDK app owns the CPP interface, so these host tools can not access the NFP through other means like NFP kernel drivers. This patch adds a CPP bridge using the rte_service API which can be enabled by a DPDK app. Interestingly, DPDK clients like OVS will not enable specific service cores, but this can be performed with a secondary process specifically enabling this CPP bridge service and therefore giving access to the NFP to those host tools.
