[dpdk-dev] [PATCH v3 3/4] eventdev: Add eventdev ethernet Rx adapter

[Nikhil Rao <nikhil.rao@intel.com>]

Add common APIs for configuring packet transfer from ethernet Rx
queues to event devices across HW & SW packet transfer mechanisms.
A detailed description of the adapter is contained in the header's
comments.

The adapter implementation uses eventdev PMDs to configure the packet
transfer if HW support is available and if not, it uses an EAL service
function that reads packets from ethernet Rx queues and injects these
as events into the event device.
