Subject: [dpdk-dev] [PATCH v3 2/7] l3fwd-power: only allow supported power library envs
Date: Fri, 19 Jun 2020 11:53:50 +0100
Message-ID: <d18a8cbe3ef4763cd6de3c64269fad6e47b37fde.1592563994.git.anatoly.burakov@intel.com> (raw)
In-Reply-To: <cover.1592563994.git.anatoly.burakov@intel.com>
In-Reply-To: <cover.1592563994.git.anatoly.burakov@intel.com>

Currently, l3fwd-power will attempt to run even if the power env
is set to KVM, which is not supported. Fix this by preventing the
app from initializing unless the env is set to one of the supported
modes.
