Subject: [U-Boot] [PATCH v2 02/10] net: calxedaxgmac: enable rx cut-thru
Date: Wed, 12 Jun 2013 22:24:46 -0500	[thread overview]
Message-ID: <1371093894-16424-2-git-send-email-robherring2@gmail.com> (raw)
In-Reply-To: <1371093894-16424-1-git-send-email-robherring2@gmail.com>

From: Rob Herring <rob.herring@calxeda.com>

There is no reason to wait for the entire frame to start DMA on receive,
so enable rx cut-thru for better performance.
