Message-ID: <1287088665-22135-3-git-send-email-mcarlson@broadcom.com> Date: Thu, 14 Oct 2010 13:37:39 -0700 From: "Matt Carlson" <mcarlson@...adcom.com> To: davem@...emloft.net cc: netdev@...r.kernel.org, andy@...yhouse.net, mcarlson@...adcom.com Subject: [PATCH net-next 2/8] tg3: Disable unused transmit rings This patch allows the driver to disable the additional transmit rings available on the 5717 and 5719 devices. This is not strictly necessary, but is done anyways for correctness.
