This driver was apparently overlooked in the processes.

phylib: preserve ifreq parameter when calling gener
The phy_mii_ioctl() function unnecessarily throws away the original ifreq.
We need access to the ifreq in order to support PHYs that can perform
hardware time stamping.

Two maverick drivers filter the ioctl commands passed to phy_mii_ioctl().
This is unnecessary since phylib will check the command in any case.

This PTP clock simply uses the NTP time adjustment system calls. The
driver can be used in systems that lack a special hardware PTP clock.

I think that the change was not about reducing scheduling
latency. Rather, the idea was simply to allow mdio bus drivers that
sleep.
