Yes.

No they are network related co processors. Not the eventdev device. The eventdev
HW is abstracted through driver/event/octeontx

Yes.

A PKOVF PCIe VF device has 8 Tx queues which can be from any MAC interface. The
created ethdev ports maps to each physical MAC interface.

One octeontx eventdev port is mapped as one octeontx ethdev Rx queue.
