Hi, Is there a way to force the items allocated from a mempool to have a certain alignment? I've attempted to add: . #ifdef RTE_MEMPOOL_ALIGN #undef RTE_MEMPOOL_ALIGN #endif #define RTE_MEMPOOL_ALIGN 512 . Before including the rte mempool header, but the pointers i get from rte_mempool_get are still aligned to 64. Thanks -- BR, Filip +48 666 369 823
