Date: Thu, 19 Jun 2008 17:18:36 -0400 From: Andy Gospodarek <andy@...yhouse.net> To: netdev@...r.kernel.org Cc: jeffrey.t.kirsher@...el.com, jesse.brandeburg@...el.com Subject: [PATCH 1/4] e1000: disable TSO workaround on 82544 It appears that the 82544 does not need the TSO workaround needed on other chips.
