Subject: [PATCH] cxgb3 - convert to user struct device instead of class_device
Commit 43cb76d9 ("Network: convert network devices to use struct
device instead of class_device") breaks the just-merged cxgb3 driver,
since the code that was merged predates the change and was not in the
tree when Greg made the change.
This patch fixes cxgb3 to build with the change. It also removes the
private to_net_dev() macro and changes the use of bare netdev->priv in
favor of netdev_priv(netdev) in the sysfs attribute functions.
I tested this on my system which has cxgb3 hardware, and it looks like
all the sysfs files are created correctly and contain sane-looking
values, although I don't actually know how to test that every
attribute is working as it should.
