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'.

But where there is no detailed definition of 'value' maybe NULL. this 
leads to a lot of processing errors (some may cause segment errors). 
This patchset fixes some of them.

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
(which prototype is arg_handler_t) parameter 'value' is NULL when
parsed 'only keys'.

But where there is no detailed definition of 'value' maybe NULL, so
this patch adds it.

I would say, you can squash your 4/9 and 5/9 patch in a single commit.
As you are doing the same thing in both the patches.

The cause of the problem is the same but the symptom is different, so I split two commit.

It's okay to squash.

Hi Chengwen,

The patch looks good to me.
Please find below few minor style comments.

* [PATCH 7/9] net/virtio: 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'
(e.g. vectorized,vdpa).

Fixes: 4710e16a4a7b ("net/virtio: add parameter to enable vectorized path")
Fixes: 44d7b2e87b69 ("net/virtio: refactor devargs parsing")
Fixes: 440f03c25378 ("net/virtio: skip device probe in vDPA mode")
