The NIC can have multiple PCIe links and can be attached to multiple hosts, for example the same single NIC can be shared for multiple server units in the rack. On each PCIe link NIC can provide multiple PFs and VFs/SFs based on these ones. The full representor identifier consists of three indices - controller index, PF index, and VF or SF index (if any). This patch introduces a new API rte_eth_representor_info_get() to retrieve representor corresponding info mapping: - caller controller index and pf index. - supported representor ID ranges. - type, controller, pf and start vf/sf ID of each range. The API is useful to calculate representor from devargs to representor ID. New ethdev callback representor_info_get() is added to retrieve info from PMD driver, optional for PMD that doesn't support new devargs representor syntax.
