Subject: [PATCH 2/2] myri10ge: set 64bits consistent DMA mask
Date: Wed, 06 Aug 2008 16:15:23 +0200 [thread overview]
Message-ID: <4899B1FB.8070700@myri.com> (raw)
In-Reply-To: <4899B198.1060508@myri.com>
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.
