From 0eb8f098a2126f6ed09e4c1ee3bfcfe64eaab7d1 Mon Sep 17 00:00:00 2001 From: Alexander Lobakin Date: Wed, 15 Jan 2020 11:56:52 +0300 Subject: [PATCH] net: dsa: tag_qca: fix doubled Tx statistics [ Upstream commit bd5874da57edd001b35cf28ae737779498c16a56 ] DSA subsystem takes care of netdev statistics since commit 4ed70ce9f01c ("net: dsa: Refactor transmit path to eliminate duplication"), so any accounting inside tagger callbacks is redundant and can lead to messing up the stats. This bug is present in Qualcomm tagger since day 0.
