Subject: PATCH: ethtool power manglement hooks

Several ethernet drivers have been broken by the ethtool support because
the ioctl code used to power the interface up and down as needed. Rather
than add this to each driver call Jeff Garzik suggested we add hooks
for before/after ethtool processing.

This patch implements them which makes fixing the PM stuff easier,
as the epic100 patch to follow will show. It also cleans up the
via-velocity driver pm/ethtool logic a great deal. As per Jeff's
request the before handler is allowed to fail the operation.

Thanks A.

BTW, if you have a free moment, I don't think all your comments from
your months-ago review of net/core/ethtool.c were addressed. A
re-review would be appreciated. In the meantime, I'm hunting around for
your original review.

Jeff

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.
