net: hns3: add support clear mac statistics 

driver inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I6QRKC


CVE: NA

----------------------------------------------------------------------

Some scenes use the standard tools ethtool and ifconfig to query traffic
statistics in a specified period.To facilitate calculation, the driver
needs to clear the original statistics first. The patch provides an
customized interface for clearing MAC statistics.
