From 65e665e68d097edfe667372f13d54f3e4edcb69c Mon Sep 17 00:00:00 2001 From: Igor Russkikh Date: Thu, 19 Oct 2017 18:23:53 +0300 Subject: net: aquantia: Reset nic statistics on interface up/down Internal statistics system on chip never gets reset until hardware reboot. This is quite inconvenient in terms of ethtool statistics usage. This patch implements incremental statistics update inside of service callback. Upon nic initialization, first request is done to fetch initial stat data, current collected stat data gets cleared. Internal statistics mailbox readout is improved to save space and increase readability Signed-off-by: Pavel Belous Signed-off-by: Igor Russkikh Signed-off-by: David S.
