Subject: [dpdk-dev] [PATCH v3 07/10] app/test-pmd: change xstats to use integer ids
Date: Mon, 30 May 2016 11:48:09 +0100 [thread overview]
Message-ID: <1464605292-4599-8-git-send-email-remy.horton@intel.com> (raw)
In-Reply-To: <1464605292-4599-1-git-send-email-remy.horton@intel.com>
The current extended ethernet statistics fetching involve doing several
string operations, which causes performance issues if there are lots of
statistics and/or network interfaces. This patch changes the test-pmd
application to use the new API that seperates name string and value
queries.
