X-BeenThere: users@dpdk.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: DPDK usage discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: users-bounces@dpdk.org Sender: "users" Hi there! I would like to find out what is the policy regarding changes to the DPDK's kmod drivers such as igb_uio.ko within a DPDK's LTS release. Are these changes backward compatible? For example, is there a guarantee that an application built against 19.11.5, where igb_uio.ko received changes,would run with this driver built from 19.11.1 version? Does http://doc.dpdk.org/guides/contributing/stable.html section 8.4 apply to kmod drivers as well? Thanks. Alex Kotliarov
