Jeff Guo 60da774e6e examples: enable HW CRC strip by default 
Since VF can not disable/enable HW CRC strip for non-DPDK PF drivers,
and kernel driver almost default enable that feature, if disable it in
example app's rxmode, VF driver will report the VF launch failure. So
this patch default to enable HW CRC strip to let VF launch successful.
