> 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.
