+
+
* ``--master-lcore ID``

Testpmd Command-line Options
----------------------------

+ Disable NUMA-aware allocation of RX/TX rings and of RX memory buffers (mbufs).
* ``--port-numa-config=(port,socket)[,(port,socket)]``
In perfect filter mode, when a rule is added with queue = -1, the packet will be enqueued into the RX drop-queue.
If the drop-queue does not exist, the packet is dropped. The default value is N=127.

* ``--burst=N``
Set the number of packets per burst to N, where 1 <= N <= 512.
- The default value is 16.
+ The default value is 32.
