Subject: [dpdk-dev] [PATCH v3 3/7] l3fwd-power: code style and flow fixes
Date: Fri, 19 Jun 2020 11:53:51 +0100
Message-ID: <b58810b2e6d95a38cd3f4e912f293702e1fe47ea.1592563994.git.anatoly.burakov@intel.com> (raw)

In-Reply-To: <cover.1592563994.git.anatoly.burakov@intel.com>

Make the coding style more consistent, and the init logic control flow
more explicit.
