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().
