The second part of the work outlined in [1] and [2]. The first part is at [3].
In this patchset, the representation of devices in rte_devargs is made generic to remove some dependencies of the EAL on specific buses implementations. Following the device types being characterized by their bus, the DEVTYPE flags are updated not to reference virtual / PCI devices anymore. The device type was one of two elements expressed by these flags and the bus handle only covers one. The second is the bus scan behavior, namely "whitelist mode" or "blacklist mode". These two modes are consequently introduced as bus scan policies, expressed within a bus configuration structure. Finally, once all specialized parts have been removed from rte_devargs, a cleaner rte_devargs parser is proposed. This parser should allow following further changes without having to update its API, and is already available for third parties to build rte_devargs structures from device declarations. With this patchset, it is now possible to use any device type on the EAL command line, with either the -w or -b parameters. The bus name can be used to explicitly ask for one bus to handle a device if there is any ambiguity. Buses needs only to implement the "parse" method for their devices to be declared in this way.
