I followed the other RTE_REGEXDEV_CAPA_ definitions 
I can fix it here

> What means "retired"?

This was the original description in the rte_regexdev.h:

#define RTE_REGEX_QUEUE_PAIR_CFG_OOS_F (1ULL << 0)
/**< Out of order scan, If not set, a scan must retire after previously issued
 * in-order scans to this queue pair. If set, this scan can be retired as soon
 * as device returns completion. Application should not set out of order scan
 * flag if it needs to maintain the ingress order of scan request.

I agree with Thomas, it is not very clear, The idea was to show that a scan can return a result
From newer job/search on a specific queue before a previous job on the same queue is completed.

How about this description:

/**< RegEx device supports out of order scan.
 * Out of order scan means the response of a specific job can be returned as
 * soon as it is ready even if previous jobs on the same queue didn't complete.
