From 60aeba23101f34a690a0b0a048ffde3d023d4f3b Mon Sep 17 00:00:00 2001 From: Thomas Lange Date: Wed, 9 Mar 2011 04:41:16 +0000 Subject: [PATCH] Davinci: Do not reset EMAC TX overruns counter on read Don't reset tx_fifo_errors when reading out current EMAC stats. (tx_fifo_errors shows up as TX overruns in netdev stats.) Without this correction, the old counter value is lost every time stats are read out. Signed-off-by: Thomas Lange Signed-off-by: David S.
