I'm testing some DPDK sample under VMware. During the testing work, I find l3fwd+ ixgbe vf can work ,but L3fwd + i40evf can't work. So I reported this issue to Bjorn. From my perspective, if can add new parameter in l3fwd sample like what have already don’t in testpmd "----crc-strip enable" is a better way to resolve this issue.

Ok! Then I'd suggest changing the l3fwd default to actually *strip* CRC instead of not doing it. Lei, any comments?

Good. Let's do that!

Not from my perspective. The issue is that Lei needs some kind of work-around for l3fwd with i40evf, so I'll let Lei comment on how critical it is.
