Subject: [dpdk-dev] [PATCH 2/2] event/sw: add useful work done attribute
Date: Mon,  7 Sep 2020 17:21:49 +0100
Message-ID: <20200907162149.31454-2-harry.van.haaren@intel.com> (raw)
In-Reply-To: <20200907162149.31454-1-harry.van.haaren@intel.com>

This commit exposes if useful work is done to the service
instance. The normal service_attr_get() API can be used to
retrieve the value of the attribute.
