Functions

func CheckIPv6Subnet added in v0.15.0 

func CheckIPv6Subnet(subnetIP *IP6, mask *big.Int) bool

func DirectRouting added in v0.10.0 

func DirectRouting(ip net.IP) (bool, error)
func EnsureV4AddressOnLink(ipa IP4Net, ipn IP4Net, link netlink.Link) error

EnsureV4AddressOnLink ensures that there is only one v4 Addr on `link` within the `ipn` address space and it equals `ipa`.
