From dd11680d0e843a9e5519304a0e89dd3815439102 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Fri, 30 May 2014 13:40:08 -0300 Subject: [PATCH] net: mv643xx_eth: Count dropped packets properly This commit fixes the current dropped packet count by doing it properly, increasing the count when a packet is discarded; i.e. the packet is not processed and the driver returns NETDEV_TX_OK.
