450  * @ingroup mgmt
451  * @brief Perform a management action.
452  *
453  * @par Description
454  * This is the top level "exec" handler for the driver. It
455  * performs the following:
456  *  - Checks that the qualifier portion of the name begins with my qualifier (ocs).
457  *  - If the remaining part of the name matches an action that is known at this level,
458  *    calls the correct function to perform the action.
459  *  - If the name is not known, sends the request to the back-ends to fulfill (if possible).
460  *  - If the request has not been fulfilled by the back-end, passes the request to each of the
461  *    children (domains) to have them (recursively) try to respond.
462  *
463  *  In passing the request to other entities, the request is considered to be handled
464  *  if the function returns 0.
465  *
466  * @param ocs Pointer to the ocs structure.
467  * @param action Name of the action to be performed.
468  * @param arg_in Pointer to an argument being passed to the action.
469  * @param arg_in_length Length of the argument pointed to by @c arg_in.
470  * @param arg_out Pointer to an argument being passed to the action.
471  * @param arg_out_length Length of the argument pointed to by @c arg_out.
472  *
473  * @return Returns 0 if the action was completed, or -1 otherwise.
