Hi, when closing & creating the new "net_pcap" device in the same instance fails on v17.05 because the device shows nb_rx_queues & nb_tx_queues = 0 from rte_eth_dev_info_get(). When the application configures the pcap dev first time, it works fine (rx & tx queues = 1) and then closes the device. When trying to configure a new pcap device with different configuration, The device has zero rx & tx queues because it seems to be saving the settings from rte_eth_dev_close(). This behavior is observed from v17.05 with the commit: "net/virtio: fix crash when closing twice" (id: 0e78cfddc0851a0a12da0257758fe011ec507495). Wondering if it's a bug or an expected behavior ?.
