The new Global Device Syntax [1] is used to identify a device with full bus, class and driver description, example: -a bus=pci,addr=82:00.0/class=eth/driver=mlx5,...
This patchset fixes bugs and enable global device syntax with backward compatibility by: - unify devargs memory buffer cleanup - parse name from bus callback - try new global syntax parsing firstly and fallback to legacy parsing. History: V1: - Inital version V2: - add devargs.src as complete source dev string - change devargs.data to scratch buffer - add rte_devargs_free() to release scratch memory - change name policy to align with rte_eth_iterator_init() - remove PCI bus fix as name already resolved in rte_devargs_parse(). V3: - remove devargs.src - rename rte_devargs_free() to rte_devargs_reset() - add bus callback api to resolve devargs.
