Subject: [dpdk-dev] [PATCH v4 5/8] drivers/net/i40e: change xstats to use integer ids
Date: Mon, 13 Jun 2016 16:51:58 +0100 [thread overview]
Message-ID: <1465833121-26953-6-git-send-email-remy.horton@intel.com> (raw)
In-Reply-To: <1465833121-26953-1-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 i40e driver
to use the new API that seperates name string and value queries.
Signed-off-by: Remy Horton <remy.horton@intel.com>
