Subject: [dpdk-dev] [PATCH v2 07/13] mbuf: move metadata macros to rte_port library
Date: Thu, 11 Sep 2014 14:15:41 +0100 [thread overview]
Message-ID: <1410441347-22840-8-git-send-email-bruce.richardson@intel.com> (raw)
In-Reply-To: <1410441347-22840-1-git-send-email-bruce.richardson@intel.com>
The metadata macros are only used by libs and apps using the rte_port
packet framework library, so move them to a header file there.
