In some usages, kvlist is processed one time in rte_kvargs_process(),
and it is processed a second time if need to check whether it was matched.
In order to simplify implementation of kvargs checks, a new callback
may be used for "no match" cases.
The change of the function prototype would be as below:
int
rte_kvargs_process(const struct rte_kvargs *kvlist,
const char *key_match,
- arg_handler_t handler,
+ arg_handler_t match_handler,
+ arg_handler_t no_match_handler,
void *opaque_arg)
