[dpdk-dev] [PATCH 0/8] app/eventdev: add event eth Rx adapter support

The eventdev application uses producer lcores to inject packets as events
into the event device. This approach is suitable for doing synthetic
performance benchmarks. In most real-world scenarios the packets are
received by an Ethernet device.

The Event Ethernet Rx Adapter library enables packet transfer between
ethernet dev and event dev transparently. This patch series adds an option
'--prod_type_ethdev' to configure the attached Ethernet devices as Rx adapters
and use them as producers instead of using synthetic producer cores. Also, this
is an RX only case.

The application has been verified on both sw and hw event devices using the

./build/app/dpdk-test-eventdev -c 0xfffff1 -s 0xf0000 --vdev="event_*"
-- --wlcores 12 --test perf_queue --verbose 20 --stlist=a
