Hi Team,
When I used PKTGEN by X710VF, I found that PKTGEN failed to be initialized. The reason is that VF has no ability to disable HW CRC strip. But it's defaulted to be disabled in PKTGEN because the global variable(hw_strip_crc) is set to 0 by default.
As we know PF can support to disable HW CRC strip. Can we add a function which can distinguish between PF and VF?
Thanks & Regards,
Chengbo Gao

If you look closer their is a command line flag to change the hw_strip_crc variable, just add or remove ‘--crc-strip’ from the command line.
