Several ethernet drivers have been broken by the ethtool support because

To be more specific, the new ethtool_ops feature bypasses code in net
drivers which did one of two things:
* power up the hardware, perform the ioctl, and power down the hardware
or
* fail if netif_running() is false, indicating the driver's requirement
that MII and ethtool operations only occur when the interface is up
(thereby ignoring the power management issues)
Also, CC net driver patches to me and netdev, pretty please with sugar
on it.
