From 952484610cc2f67303be4feedb0e52a519c31470 Mon Sep 17 00:00:00 2001 From: Intiyaz Basha Date: Fri, 3 Nov 2017 14:32:33 -0700 Subject: [PATCH] liquidio: do not consider packets dropped by network stack as driver Rx dropped netdev->rx_dropped was including packets dropped by napi_gro_receive. If a packet is dropped by network stack, it should not be counted under driver Rx dropped. Made necessary changes to not include network stack drops under netdev->rx_dropped.
