These seem to be in the driver and I have no control of that code. Including the maintainers.

>     Pktgen can only set the hw_strip_crc for the port only when the command line uses —crc-strip option. In this case the port was set by the PF to hw-strip and Pktgen is resetting that value back to zero, so just add the —crc-strip option to pktgen for the VF port.
