Ethtool and iproute2 tool statistics are wrong

[barry-shang]

When we use the iavf-4.13.3 to test the VF functional rx checksum on the XL710 and E810.

we found the follow issue:

when PF tests rx checksum. the ethtool command shows error packets and iproute2 also shows the number of errors.

However, when VF tests rx checksum, no error packets are displayed in the ethtool command, and iproute2 does not display the number of errors.
