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 enables global device syntax with backward compatibility by: - unify devargs memory cleanup - parse name from bus parameters - 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_drvargs_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().
