Functions

func Init 

func Init(goes string)

func NetPortCleanup added in v1.8.7 

func NetPortCleanup(t *testing.T, ns string, ifname string, vlan int)

func NetPortConfig added in v1.8.7 

func NetPortConfig(t *testing.T, ns string, netport string, vlan int) (ifname string)

add/del netport in netns, either as dataport or member of bridge

Types

type DummyIf 

type DummyIf struct {
	Ifname string
	Ifa    string
}

type NetDev 

type NetDev struct {
	Kind string

	NetPort string // lookup key for NetPortFile to Ifname
	Vlan    int    // for PORT_VLAN
	Ifname  string

	Netns    string
	Ifa      string
	DummyIfs []DummyIf
	Routes   []Route
	Remotes  []string
	Lowers   []PortVlan
}

NetDev describes a network interface configuration. default PORT sets ifa for ifname derived from NetPort BRIDGE adds a linux bridge device with ifname and ifa, plus its vlan members PORT_VLAN adds a linux vlan device to ifname derived from NetPort with ifa initial values filled from NetDev[], then DevKind and Ifname updated

type NetDevs 

type NetDevs []NetDev

NetDevs describe all of the interfaces in the virtual network under test.

func (NetDevs) Test 

func (netdevs NetDevs) Test(t *testing.T, tests ...test.Tester)

netdevs list the interface configurations of the network under test

type PortVlan added in v1.8.7 

type PortVlan struct {
	NetPort string
	Vlan    int
