Hi Andrew!

I think I've converted all phy drivers while removing support for
SIOCSHWTSTAMP/SIOCGHWTSTAMP from netdev ioctl. I believe it's impossible right
now to reach SIOCSHWTSTAMP path of phy_mii_ioctl via ioctl on net device.

Is it possible to have ioctl on phy device directly without involving netdev?
