Ethtool and iproute2 tool statistics are wrong for E810 NIC card

[barry-shang]

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

why do you request the ssu logs ? Are you try to reproduce it ? I have told you this issue can reproduce easily. now I don't have the environment.  so I can't provide any infomation.

In addition, this is a generial issue. if you want to reproduce this issue. you can use any linux shipped with your iavf driver.
