This series adds support for eventmode helper library and l2fwd-event
application.
First 13 patches creates a new l2fwd application (l2fwd-event). Minor
code reorganization is done to faciliate seamless integration of
eventmode.
Next 22 patches adds eventmode helper library. This library abstracts
the configuration of event device & Rx-Tx event adapters. The library
can be extended to allow users to control all the configuration
exposed by adapters and eth device.
Last 4 patches implements eventmode in l2fwd-event application. With
event device and adapters, fine tuned threads (based on dev
capabilities) can be drafted to maximize performance. Eventmode
library facilitates this and l2fwd-event demonstrates this usage.
With the introduction of eventmode helper library, any poll mode
application can be converted to an eventmode application with simple
steps, enabling multi-core scaling and dynamic load balancing to
various example applications.
Usage:
./l2fwd-event -- <EAL args> -- <l2fwd args> -- --transfer-mode 1
The above command would invoke eventmode and with the default conf
loaded, traffic on one port would be delivered to all enabled cores.
Planned features,
1. Eventmode helper library doesn't intialize ethdev. Since all
applications already do this, eventmode helper would start
from reconfiguring.
2. All features of eventdev and adapters can be exposed to the user
using common CL arguments. The framework for achieving the same
is already in place. It has to be extended to support more
features.
3. Documentation is pending.
Created new app based on discussions,

Tested with nicvf eth PMD and event_octeontx event PMD on Marvell's
CN83XX platform.
