Subject: [dpdk-dev] [PATCH v3 5/7] app/proc-info: dump rx and tx descriptor info
Date: Wed, 15 Jul 2020 14:22:26 -0700
Message-ID: <20200715212228.28010-6-stephen@networkplumber.org> (raw)
In-Reply-To: <20200715212228.28010-1-stephen@networkplumber.org>

Many drivers will report per queue info for both rx and tx
as well as how many descriptors are in use.
