Subject: [PATCH 7/8] app/eventdev: add service core configuration
Date: Wed, 18 Oct 2017 18:09:07 +0530	[thread overview]
Message-ID: <1508330348-30060-8-git-send-email-pbhagavatula@caviumnetworks.com> (raw)
In-Reply-To: <1508330348-30060-1-git-send-email-pbhagavatula@caviumnetworks.com>

Add service core configuration for Rx adapter. The configuration picks
the least used service core to run the service on.
