From: Petri Gynther Date: Fri, 10 Jul 2015 23:20:00 +0000 (-0700) Subject: net: bcmgenet: fix accounting of packet drops vs errors X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c590032f9ab8d03aab235a7601db22a267c2d958;p=linux-beck.git net: bcmgenet: fix accounting of packet drops vs errors bcmgenet driver needs to separate packet drops from packet errors. When the driver has to drop a *good* packet, due to lack of buffers or replacement skbs, increment only dev->stats.[rx|tx]_dropped. When the driver encounters a bad Rx packet or Tx error, increment only dev->stats.[rx|tx]_errors + relevant detailed error counter. Signed-off-by: Petri Gynther Signed-off-by: David S.
