From 77970ea50b8e7ee9733a6589bf61ed9c02f20ee9 Mon Sep 17 00:00:00 2001 From: Brice Goglin <brice@myri.com> Date: Wed, 6 Aug 2008 16:15:23 +0200 Subject: [PATCH] myri10ge: set 64bits consistent DMA mask Set 64bits consistent DMA mask since it improves performance in some cases. No need to check the return value since it is not required for the driver to work.
