So, is following correct: BGX is MAC interface, in ingress it consists of single PKIVF (packet input) device, in egress it consists of PKOVF (packet output) devices. PKIVF and PKOVF are physical eventdev devices. First physical devices are probed, later virtual ethdev is created which gets/puts packets into these event devices. A graph in documentation can be very helpful for this. Also patchset can create multiple ethdev ports, why is this? And how eventdev - ethdev port mapping done for that case?
