Subject: [EXT] [PATCH v2 22/44] net/mvneta: fix segment fault when parse devargs

External Email

----------------------------------------------------------------------
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'.

Fixes: 4ccc8d770d3b ("net/mvneta: add PMD skeleton")
