* Get, set, or probe feature data of the device. The feature is selected
* using the FEATURE_MASK portion of the flags field. Support for a feature
* can be probed by setting both the FEATURE_MASK and PROBE bits. A probe
* may optionally include the GET and/or SET bits to determine read vs write
* access of the feature respectively. Probing a feature will return success
* if the feature is supported and all of the optionally indicated GET/SET
* methods are supported. The format of the data portion of the structure is
* specific to the given feature. The data portion is not required for
* probing. GET and SET are mutually exclusive, except for use with PROBE.
*
* Return 0 on success, -errno on failure.
