From f55d477bb513c9267a46d7a795fb09f73084f76f Mon Sep 17 00:00:00 2001 From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com> Date: Mon, 29 Apr 2019 10:05:05 +0000 Subject: [PATCH] net: aquantia: get total counters from DMA block aq_nic_update_ndev_stats pushes statistics to ndev->stats from system interface. This is not always good because it counts packets/bytes before any of rx filters (including mac filter). Its better to report the packet/bytes statistics from DMA counters which gives actual values of data transferred over pci. System level stats is still available via ethtool.
