 *	the driver on return.

 * @len: On return, the number of test results

 * @data: Array of test results

 *

 * Users must use %ETHTOOL_GSSET_INFO or %ETHTOOL_GDRVINFO to find the

 * number of test results that will be returned.  They must allocate a

 * buffer of the appropriate size (8 * number of results) immediately

 * following this structure.
