From: Thomas Monjalon Date: Fri, 20 Oct 2017 12:31:31 +0000 (+0530) Subject: mempool: rename addresses from physical to IOVA X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=efd785f99489478d14e1c222e243ecbd0b151507;p=dpdk.git mempool: rename addresses from physical to IOVA The struct fields phys_addr_t rte_mempool_objhdr.physaddr and rte_mempool_memhdr.phys_addr are renamed to rte_iova_t iova. The deprecated names are kept in an anonymous union to avoid breaking the API.
