In such cases, dpdk mbuf memory should not cross physical page boundary,  If it crosses, it's iova/va will be contiguous, but it's pa may or may not be contiguous. Kni pktmbuf pool api ensures that mempool is not populated with those type of mbufs(that cross page boundary). Once the pool is created, all mbufs in that pool resides with in the page limits.

ack.

Good to hear this.
