If kernel module is not there, application will run as it is without kernel control path support. When UNCI module inserted, running application creates a virtual Linux network interface (dpdk$) per DPDK port. This interface can be used by traditional Linux tools. If Userspace Network Control Interface (UNCI) kernel module (rte_unci.ko) inserted, virtual interfaces created for each DPDK port for control purposes. Created interfaces are named as dpdk#, like: $ ifconfig dpdk0; ifconfig dpdk1 dpdk0: flags=4099 mtu 1500 ether 90:e2:ba:0e:49:b9 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 dpdk1: flags=4099 mtu 1500 ether 00:1b:21:76:fa:21 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 Regular Linux commands can be issued on interfaces: $ ethtool -i dpdk0 driver: net_ixgbe version: DPDK 17.08.0-rc0 firmware-version: 0x61bf0001 expansion-rom-version: bus-info: 0000:08:00.1 supports-statistics: no supports-test: no supports-eeprom-access: yes supports-register-dump: yes supports-priv-flags: no Signed-off-by: Ferruh Yigit --- lib/librte_ether/rte_ethdev_pci.h | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) diff --git a/lib/librte_ether/rte_ethdev_pci.h b/lib/librte_ether/rte_ethdev_pci.h index 69aab03fb..a32a617d7 100644 --- a/lib/librte_ether/rte_ethdev_pci.h +++ b/lib/librte_ether/rte_ethdev_pci.h @@ -38,6 +38,13 @@ #include #include +#ifdef RTE_LIBRTE_CTRL_IF +#include +#else +#define rte_eth_control_interface_create_one(port_id) do { } while(0) +#define rte_eth_control_interface_destroy_one(port_id) do { } while(0) +#endif + /** * Copy pci device info to the Ethernet device data. * @@ -157,8 +164,12 @@ rte_eth_dev_pci_generic_probe(struct rte_pci_device *pci_dev, RTE_FUNC_PTR_OR_ERR_RET(*dev_init, -EINVAL); ret = dev_init(eth_dev); - if (ret) + if (ret) { rte_eth_dev_pci_release(eth_dev); + return ret; + } + + rte_eth_control_interface_create_one(eth_dev->data->port_id); return ret; } @@ -179,6 +190,8 @@ rte_eth_dev_pci_generic_remove(struct rte_pci_device *pci_dev, if (!eth_dev) return -ENODEV; + rte_eth_control_interface_destroy_one(eth_dev->data->port_id); + if (dev_uninit) { ret = dev_uninit(eth_dev); if (ret) -- 2.13.0
