Subject: [PATCH 1/6]: powerpc/cell spidernet burst alignment patch
Date: Fri, 18 Aug 2006 17:20:38 -0500 [thread overview]
Message-ID: <20060818222038.GH26889@austin.ibm.com> (raw)
In-Reply-To: <20060818220700.GG26889@austin.ibm.com>
This patch increases the Burst Address alignment from 64 to 1024 in the
Spidernet driver. This improves transmit performance for arge packets
from about 100Mbps to 300-400Mbps.
