Allow to write to "carrier" attribute. Devices may implement ndo_change_carrier
callback to allow changing carrier from userspace.

Do you expect drivers using implementation different than just calling
netif_carrier_on/off? Or is it supposed to also e.g. power down PHYs?

Yes, generally it can be used also for en/disable phy, for testing
purposes if hw and driver would support it.

BTW, I like this feature!
