Subject: [dpdk-stable] [PATCH v1] app/testpmd: fix DCB set failure in FreeBSD by clang
Date: Mon, 11 May 2020 10:25:04 +0000 [thread overview]
Message-ID: <20200511102504.23936-1-ting.xu@intel.com> (raw)
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.
Fixes: b57b66a97ebf ("app/testpmd: support mbuf dynamic flag")
