* [dts] [PATCH] l3fwd: optimize l3fwd performance suite
@ 2015-02-26  2:56 Yong Liu

From: Yong Liu @ 2015-02-26  2:56 UTC (permalink / raw)
  To: dts

Unify 2 ports and 4 ports performance functions, for they have the same logic.
Config IXIA flow with random source ip address, thus will seperate flows into
several queues. Remove unless plot function.
