>Description:
        Pre-5.99.6 raidctl binary cannot configure the RAIDframe device.

>How-To-Repeat:
        # raidctl -c /etc/raid0.conf raid0
        dk_lookup on device:  failed!
        RAIDFRAME: failed rf_ConfigureDisks with 2
        raidctl: ioctl (RAIDFRAME_CONFIGURE) failed: No such file or directory

>Fix:
        Provide compat ioctl, since struct RF_Config_s in raidframevar.h
        contains dev_t which has changed to 64-bit after christos-time_t merge.
