X-BeenThere: dev@dpdk.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: DPDK patches and discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dev-bounces@dpdk.org Sender: "dev" Hi All, Below is a series of patches to add a new API function to allow DPDK applications to access the private data area of the mbuf, if one exists. This eliminates the repeated code in applications to access the private data area and makes the API a bit more complete, since there are already accessor functions to access the start of the buffer, the start of data, etc. The first patch [1 of 4] adds the accessor function to rte_mbuf.h. The other three patches clean up other code to use this new function. Please let me know what you think. thanks dan v2: * Change 'md' to 'm' in rte_mbuf_to_priv(). * Remove check of m->priv_len in rte_mbuf_to_priv() to avoid confusion if used with indirect mbufs.
