430  * @ingroup mgmt
431  * @brief Perform a management action.
432  *
433  * @par Description
434  * This is the top level "exec" handler for the driver. It
435  * performs the following:
436  *  - Checks that the qualifier portion of the name begins with my qualifier (ocs).
437  *  - If the remaining part of the name matches an action that is known at this level,
438  *    calls the correct function to perform the action.
439  *  - If the name is not known, sends the request to the back-ends to fulfill (if possible).
440  *  - If the request has not been fulfilled by the back-end, passes the request to each of the
441  *    children (domains) to have them (recursively) try to respond.
442  *
443  *  In passing the request to other entities, the request is considered to be handled
444  *  if the function returns 0.
445  *
446  * @param ocs Pointer to the ocs structure.
447  * @param action Name of the action to be performed.
448  * @param arg_in Pointer to an argument being passed to the action.
449  * @param arg_in_length Length of the argument pointed to by @c arg_in.
450  * @param arg_out Pointer to an argument being passed to the action.
451  * @param arg_out_length Length of the argument pointed to by @c arg_out.
452  *
453  * @return Returns 0 if the action was completed, or -1 otherwise.
