    ioat: add 'ioat' sysfs attributes · 5669e31c

    Export driver attributes for diagnostic purposes:
    'ring_size': total number of descriptors available to the engine
    'ring_active': number of descriptors in-flight
    'capabilities': supported operation types for this channel
    'version': Intel(R) QuickData specfication revision
    
    This also allows some chattiness to be removed from the driver startup
    as this information is now available via sysfs.
