Message-Id: <20110418233120.CCB2313909@rere.qmqm.pl>
Date: Tue, 19 Apr 2011 01:31:20 +0200 (CEST)
From: Michał Mirosław <mirq-linux@...e.qmqm.pl>
To: netdev@...r.kernel.org
Cc: "David S. Miller" <davem@...emloft.net>
Subject: [PATCH v2] net: chelsio: convert to hw_features
Also remove flags that were not used or are now redundant to hw_features bits.
No device had UDP_CSUM_CAPABLE set.
