From 8990f468ae9010ab0af4be8f51bf7ab833a67202 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 20 Sep 2010 00:12:11 +0000 Subject: net: rx_dropped accounting Under load, netif_rx() can drop incoming packets but administrators dont have a chance to spot which device needs some tuning (RPS activation for example) This patch adds rx_dropped accounting in vlans and tunnels.
