From 5944701df90d9577658e2354cc27c4ceaeca30fe Mon Sep 17 00:00:00 2001 From: stephen hemminger Date: Fri, 6 Jan 2017 19:12:53 -0800 Subject: [PATCH] net: remove useless memset's in drivers get_stats64 In dev_get_stats() the statistic structure storage has already been zeroed. Therefore network drivers do not need to call memset() again. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
