The motivation for this work started with the realization while
untangling the ethtool/netlink and PHY library that tests like those:
dev->netdev_ops == &foo_ops would be defeated by the way DSA overloads
the DSA net_device operations. A better solution needed to be found.

You are correct that we could just put a call to phy_mii_ioctl() here as
well and avoid having drivers have to use phy_do_ioctl_running or roll
their own.
