Functions ¶

func GetNetlinkHandle ¶

func GetNetlinkHandle(urlString string) (*netlink.Handle, error)

GetNetlinkHandle - mechanism to netlink.Handle for the NetNS specified in mechanism

Types ¶

type Link ¶

type Link interface {
	AddAddress(ip string) error
	DeleteAddress(ip string) error
	MoveToNetns(target netns.NsHandle) error
	SetAdminState(state State) error
	SetName(name string) error
	GetName() string
	GetLink() netlink.Link
}

Link represents network interface and specifies operations that can be performed on that interface.

func FindHostDevice ¶

func FindHostDevice(pciAddress, name string, namespaces ...netns.NsHandle) (Link, error)

FindHostDevice returns a new instance of link representing host device, based on the PCI address and/or target interface name.

type State ¶

type State uint

State defines admin state of the network interface

const (
	// DOWN is link admin state down
	DOWN State = iota
	// UP is link admin state down
	UP
)
