Subject: [dpdk-dev] [PATCH v2 11/16] app/testpmd: fix missing initialization in the RSS hash show command
Date: Fri, 30 Oct 2015 19:55:14 +0100 [thread overview]
Message-ID: <1446231319-8185-12-git-send-email-adrien.mazarguil@6wind.com> (raw)
In-Reply-To: <1446231319-8185-1-git-send-email-adrien.mazarguil@6wind.com>
The "show port X rss-hash" command sometimes displays garbage instead of the
expected RSS hash key because the maximum key length is undefined. When the
requested key is too large to fit in the buffer,
rte_eth_dev_rss_hash_conf_get() does not update it.
