From a339f1c881fdb8092ef9b118610307e10e885fc8 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Wed, 21 May 2008 14:13:47 -0700 Subject: [PATCH] bridge: Use on-device stats instead of private ones. Even though bridges require 6 fields from struct net_device_stats, the on-device stats are always there, so we may just use them. The br_dev_get_stats is no longer required after this.
