> Subject: [PATCH v2 20/44] net/mana: fix segment fault when parse devargs
>
> The rte_kvargs_process() was used to parse KV pairs, it also supports to parse
> 'only keys' (e.g. socket_id) type. And the callback function parameter
> 'value' is
> NULL when parsed 'only keys'.
>
> This patch fixes segment fault when parse input args with 'only keys'.
