From 6e46e2d821bb22b285ae8187959096b65d063b0d Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Thu, 28 Feb 2019 18:14:03 +0100 Subject: [PATCH] net: dsa: mv88e6xxx: Fix u64 statistics The switch maintains u64 counters for the number of octets sent and received. These are kept as two u32's which need to be combined. Fix the combing, which wrongly worked on u16's.
