Subject: [dpdk-dev] [PATCH 08/20] net/ena/base: add ENI stats
Date: Thu, 17 Sep 2020 07:30:23 +0200
Message-ID: <20200917053035.1889989-9-mk@semihalf.com> (raw)
In-Reply-To: <20200917053035.1889989-1-mk@semihalf.com>

The Elastic Netfwork Interface (ENI) stats can be acquired from the HW.

They can provide advanced values which can be further used by the
application for better flow management.

It isn't available to the DPDK application, yet. The PMD must expose
them directly.
