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" Even if whitelist of devices is provided, rte_pci_probe() increments the probed counter for all the devices present in the system. If probe fails for all the whitelisted devices it still return success because failed and probed counts don't match. This patch increments probed count only when devices are actually probed.
