From: Santosh Shukla Date: Fri, 20 Oct 2017 12:31:32 +0000 (+0530) Subject: mbuf: rename physical address to IOVA X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=455da5453987;p=dpdk.git mbuf: rename physical address to IOVA Rename buf_physaddr to buf_iova. Keep the deprecated name in an anonymous union to avoid breaking the API.
