I'm not sure about that. We need Richards input.

The code in phy_mii_ioctl() allows the MAC to be bypassed, it goes
straight to a PHY based stamper. It could be the MAC has no idea the
PHY has this capability, so it has not implemented the .ndo?

It might be we need to hoist the code from phy_mii_ioctl() into
dev_{sg}et_hwtstamp()?
