Eventdev-based networking applications require a component to dequeue
packets from NIC Rx queues and inject them into eventdev queues[1]. While
some platforms (e.g. Cavium Octeontx) do this operation in hardware, other
platforms use software.
This patchset introduces an ethernet Rx event adapter t

Good point.
Can we realize the same use case like below?

Hi Jerin and all,
There are a few inconsistencies/complexities that I ran into with the
implementation of the SW Rx event adapter, I have first summarized this
email thread bringing together details scattered across various
exchanges then I want to check if there are changes possible that wou

OK. I was thinking like there will be fixed name for the rx_adapter
service like "eth_rx_adapter_%d"(%d for adapter id)

Makes sense. Are you thinking the helper function would do stop + reconfig with
additional port + start + setup port, or just setup the port with an ID the app
supplies
