Message-Id: <20110418233121.AEC4913A68@rere.qmqm.pl>
Date: Tue, 19 Apr 2011 01:31:21 +0200 (CEST)
From: Michał Mirosław <mirq-linux@...e.qmqm.pl>
To: netdev@...r.kernel.org
Cc: Shreyas Bhatewara <sbhatewara@...are.com>,

Subject: [PATCH] net: vmxnet3: convert to hw_features
This also removes private feature flags that were always set to true.
You may want to move vmxnet3_set_features() to vmxnet3_drv.c as a following
cleanup.
