> Subject: [PATCH v1] app/testpmd: fix DCB set failure in FreeBSD by clang
>
> When set DCB in testpmd by clang, there is a segmentation fault.
> It is because the local variable rss_conf in get_eth_dcb_conf() is not
> cleared,
> so that the pointer member variable rss_key has a random address, which
> leads to an error in the following processing. This patch initialized the
> local
> variable rss_conf to avoid random address.
