Subject: [net-next 2/6] e1000e: Enable DMA Burst Mode on 82574 by default.
Date: Fri, 27 Apr 2012 02:36:49 -0700 [thread overview]
Message-ID: <1335519413-1892-3-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1335519413-1892-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Matthew Vick <matthew.vick@intel.com>
Performance testing has shown that enabling DMA burst on 82574
improves performance on small packets, so enable it by default.
