If you don't make bullets, all lines are rendered on the same line, without any separator:

Returns
        On success return pointer to sym-session.
        On failure returns NULL and rte_errno is set to the error code. EINVAL on invalid arguments. ENOMEM on memory error for session allocation. ENOTSUP if device doesn't support session configuration.
"

In general, you must check the HTML rendering of the doc changes.

I am fixing while pulling.
