  Since VF has no ability to disable/enable HW CRC strip for non-DPDK PF
drivers, and for most case of kernel driver default enable HW CRC strip,
if disable HW CRC strip in app's rxmode, VF driver will return fail and
result the VF launch failure. So this patch default to enable HW CRC strip
to let VF launch successful.
