Subject: [dpdk-dev] [PATCH] app/testpmd: limit number of forwarding cores
Date: Mon, 27 Jun 2016 23:35:19 +0100	[thread overview]
Message-ID: <1467066919-135951-1-git-send-email-pablo.de.lara.guarch@intel.com> (raw)

Number of forwarding cores must be equal or less than
number of forwarding streams, otherwise two cores
would try to use a same queue on a port, which is not allowed.

Fixes: f2bb7ae1d204 ("app/testpmd: handle all Rx queues in RSS setup")
