* Note : I removed media - bay details from the feature stuff , I believe it ' s
* not worth it , the media - bay driver can directly use the mac - io
* ASIC registers .
*
* Implementation note : Currently , none of these functions will block .
* However , they may internally protect themselves with a spinlock
* for way too long . Be prepared for at least some of these to block
* in the future .
*
* Unless specifically defined , the result code is assumed to be an
* error when negative , 0 is the default success result . Some functions
* may return additional positive result values .
*
* To keep implementation simple , all feature calls are assumed to have
* the prototype parameters ( struct device_node * node , int value ) .
* When either is not used , pass 0.
