Typo: "concatenate"
And it's really good to have those split strings combined. Thanks.

This patch overall looks good to me.

But there're some warnings about coding styles reported. http://mails.dpdk.org/archives/test-report/2021-June/199047.html
Not all of them makes sense.
But can you check ones with QUOTED_WHITESPACE_BEFORE_NEWLINE, UNSPECIFIED_INT, EMBEDDED_FUNCTION_NAME?
The latter two type of warnings are legacy issues but it'll be good to have them fixed.
