From mboxrd@z Thu Jan 1 00:00:00 1970 From: Vladimir Koutny Date: Thu, 28 Nov 2013 10:38:40 +0100 Subject: [U-Boot] [PATCH] am335x: cpsw: optimize cpsw_recv to increase network performance Message-ID: <52970F20.6070401@streamunlimited.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de In 48ec5291, only TX path was optimized; this does the same also for RX path. This results in huge increase of TFTP throughput on custom am3352 board (from 312KiB/s to 1.8MiB/s) and eliminates occasional transfer timeouts.
