From 511d22247be767bbf275ee7a5a388c4f009aa0c1 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 7 Jul 2010 20:44:24 +0000 Subject: [PATCH] tg3: 64 bit stats on all arches Now core network is able to handle 64 bit netdevice stats on 32 bit arches, we can provide them for tg3, since hardware maintains 64 bit counters.
