net: ethtool: Add a command to expose current time stamping layer
Time stamping on network packets may happen either in the MAC or in
the PHY, but not both. In preparation for making the choice
selectable, expose both the current layers via ethtool.
In accordance with the kernel implementation as it stands, the current
layer will always read as "phy" when a PHY time stamping device is
present. Future patches will allow changing the current layer
administratively.
