From f613ed665bb3ec49edc4907bd8799e3a2de47df5 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Tue, 1 Aug 2017 15:00:36 -0700 Subject: net: dsa: Add support for 64-bit statistics DSA slave network devices maintain a pair of bytes and packets counters for each directions, but these are not 64-bit capable. Re-use pcpu_sw_netstats which contains exactly what we need for that purpose and update the code path to report 64-bit capable statistics. Signed-off-by: Florian Fainelli Signed-off-by: David S.
