 * Description:
 *
 * get_settings:
 *	@get_settings is passed an &ethtool_cmd to fill in.  It returns
 *	an negative errno or zero.
 *
 * set_settings:
 *	@set_settings is passed an &ethtool_cmd and should attempt to set
 *	all the settings this device supports.  It may return an error value
 *	if something goes wrong (otherwise 0).
 *
 * get_eeprom:
 *	Should fill in the magic field.  Don't need to check len for zero
 *	or wraparound.  Fill in the data argument with the eeprom values
 *	from offset to offset + len.  Update len to the amount read.
 *	Returns an error or zero.
 *
 * set_eeprom:
 *	Should validate the magic field.  Don't need to check len for zero
 *	or wraparound.  Update len to the amount written.  Returns an error
 *	or zero.
