| Subject: net: libwx: fix multicast packets received count |
| |
| From: Jiawen Wu <jiawenwu@trustnetic.com> |
| |
| commit 2b30a3d1ec2538a1fd363fde746b9fe1d38abc77 upstream. |
| |
| Multicast good packets received by PF rings that pass ethternet MAC |
| address filtering are counted for rtnl_link_stats64.multicast. The |
| counter is not cleared on read. Fix the duplicate counting on updating |
| statistics. |
| |
| Fixes: 46b92e10d631 ("net: libwx: support hardware statistics") |
