Subject: [PATCH 3/5] igb: increase delay for copper link setup
Date: Tue, 31 Mar 2009 23:38:38 -0700	[thread overview]
Message-ID: <20090401063837.3046.221.stgit@lost.foo-projects.org> (raw)
In-Reply-To: <20090401063759.3046.89960.stgit@lost.foo-projects.org>

From: Alexander Duyck <alexander.h.duyck@intel.com>

Increase the delay for copper phy init from 15ms to 100ms.  This is to
address issues seen in which ethtool -t was failing in some cases on 82576
based adapters.
