From 281e8b2fdf8e4ef366b899453cae50e09b577ada Mon Sep 17 00:00:00 2001 From: Amir Vadai Date: Wed, 17 Feb 2016 17:24:22 +0200 Subject: [PATCH] net/mlx4_en: Count HW buffer overrun only once RdropOvflw counts overrun of HW buffer, therefore should be used for rx_fifo_errors only. Currently RdropOvflw counter is mistakenly also set into rx_missed_errors and rx_over_errors too, which makes the device total dropped packets accounting to show wrong results. Fix that. Use it for rx_fifo_errors only.
