[dpdk-dev] [PATCH v1 0/7] eal: support global syntax

[Xueming Li]

New Global device syntax [1] is used to identify a device with full bus,
class and driver description, example:
 -a bus=pci,id=82:00.0/class=eth/driver=mlx5,dv_flow_en=1

This patch enables global syntax with backward compatibility by trying
new global syntax firstly and fallback to legacy parsing.

For PCI device, BDF is retrived from the "id" attribute of bus section,
parse from device name if "id" not available.


Depends-on: patch-86058 ("ethdev: refactor representor infrastructure")
