Subject: [dpdk-dev] [PATCH v3 04/10] drivers/net/fm10k: change xstats to use integer ids
Date: Mon, 30 May 2016 11:48:06 +0100 [thread overview]
Message-ID: <1464605292-4599-5-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 fm10k driver
to use the new API that seperates name string and value queries.
