This patchset introduces a new EAL API for querying devices,
filtered by arbitrary properties.
The following elements are introduced to this end:
* A new object, "rte_class", is used to describe
the device class abstraction layer (eth, crypto, ...).
* Both rte_bus and rte_class now offer a way to
list their devices and filter the result
using locally defined properties.
* The rte_dev API now has an rte_dev_iterator, which
is the way for the user to define the device filter
and iterate upon the resulting set.
As an example, the "eth" device class is implemented.
Additionally, the device filters for
+ rte_bus_pci
+ rte_bus_vdev
+ rte_class_eth
are implemented and can be used with some
properties each, to show how to extend those.
Some example of filters:
"bus=pci/class=eth"
"bus=pci"
"class=eth"
"class=eth,name=net_ring0"
"bus=pci,id=00:00.0"
"bus=vdev,driver=net_ring"
