PATCH 1/3 ieee1394: convert to net_device_ops

Convert to net_device_ops.

Use the network_device_stats field in network_device.

Just in case that this is meant to go through net(dev?)-2.6.git rather than linux1394-2.6.git:

You mean 2.6.29-rc2?

Is David going to take patches 1/3...3/3? If so, here is:

Or shall I take them through linux1394-2.6.git?
