Subject: [RFC PATCH v1 4/4] testpmd: make use of per-PMD TxRx parameters
Date: Wed,  7 Mar 2018 12:08:51 +0000	[thread overview]
Message-ID: <20180307120851.5822-5-remy.horton@intel.com> (raw)
In-Reply-To: <20180307120851.5822-1-remy.horton@intel.com>

The optimal values of several transmission & reception related
parameters, such as burst sizes, descriptor ring sizes, and number
of queues, varies between different network interface devices. This
patch allows testpmd to make use of per-PMD tuned parameter values.
