From ce1e4060441a2e8e292fc0fc9b92d1111c467a8e Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Thu, 28 Feb 2019 18:14:03 +0100 Subject: net: dsa: mv88e6xxx: Fix u64 statistics [ Upstream commit 6e46e2d821bb22b285ae8187959096b65d063b0d ] 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.
