Message-Id: <20110418233121.1726C13A64@rere.qmqm.pl>
Date: Tue, 19 Apr 2011 01:31:20 +0200 (CEST)
From: Michał Mirosław <mirq-linux@...e.qmqm.pl>

Subject: [PATCH] net: s2io: convert to hw_features
This removes advertising HW_CSUM as driver does not support it.
Note: driver advertises TSO6 but not IPV6_CSUM - bug maybe?
