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, I am developing an application with DPDK (v17.11) using a concatenation of pipelines. Now I find myself on the definition of an ACL table and more precisely the format of the ACL fields. One of the parameters of this field format is the 'offset', which indicates the number of bytes till the start of the field to check. All the examples I have seen so far assume that an offset value of 0 means the start of Ethernet header and not the start of rte_mbuf struct. Is there a way to place the offset start at the rte_mbuf struct? If not, I think that it would be a useful enhancement. That's why I propose it in the developers mailing list. What do you think about this? Thanks a lot for your attention. -- Victor
