Subject: [patch 5/5] [PATCH] qeth: change checksumming default for HiperSockets

From: [email-masked]
Date: Tue, 09 Mar 2010 07:36:57 +0100

From: Frank Blaschka <[email-masked]>

Deactivate inbound checksumming on HiperSocket is a valid but
dangerous optimization in case the frame is routed from an OSA
network to an HiperSockets network. To go for sure we change the
default to software checksumming.
