[dpdk-dev] [PATCH v2 5/5] devargs: enable global device syntax devargs

[Xueming Li]

When parsing a device argument, try to parse new global device syntax
firstly, fallback to legacy syntax parsing on error.

Example of new global device syntax:
 -a bus=pci,addr=82:00.0/class=eth/driver=mlx5,dv_flow_en=1
