The mempool for this scenario is allocated using rte_mempool_create() and all associated documentation/source seems to indicate the pool returned should be virtually contiguous. Have any of you experienced this failure and figured out a resolution? Thanks, -Anshu ^ permalink raw reply [flat|nested] 5+ messages in thread
