dsa_master_ioctl() is in the process of getting converted to a different API, where we won't have access to a struct ifreq * anymore, but rather, to a struct kernel_hwtstamp_config. Since ds->ops->port_hwtstamp_get() still uses struct ifreq *, this creates a difficult situation where we have to make up such a dummy pointer. The conversion is a bit messy, because it forces a "good" implementation of ds->ops->port_hwtstamp_get() to return -EFAULT in copy_to_user() because of the NULL ifr->ifr_data pointer. However, it works, and it is only a transient step until ds->ops->port_hwtstamp_get() gets converted to the new API which passes struct kernel_hwtstamp_config and does not call copy_to_user().
