Subject: [PATCH 192/283] net: hns3: add support clear mac statistics
driver inclusion
category: feature
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8EN3D
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.
