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, DPDK masters, I am debugging a `imissed` issue when we are using DPDK. We notice that imissed increase even when the traffic is slow. We are using x520 nic and ixgbe driver. Via check the code, imissed comes from rx_total_missed_packets in ixgbe. But what's the possible reason that make rx_total_missed_packets increase in ixgbe? Highly appreciated your reply if you have any clues on this.
