This patchset adds common initialization code required for using applications in event mode. The APIs exposed, abstracts the complex configuration options exposed by eventdev, ethdev & eth rx adapter. Also, this enables the usage of multiple workers fine tuned for the features of the underlying hardware.
With these APIs, existing poll mode applications can be made event driven easily, and the applications can better leverage the event mode's capabilities. L2fwd application has been made event-driven to demonstrate the usage of helper APIs. Tested with nicvf eth PMD and event_octeontx event PMD on Cavium's CN83XX platform.
