Constants

const (
	SIOCAIFADDR_IN6       = (unix.SIOCAIFADDR & 0xe000ffff) | (uint(unsafe.Sizeof(addrIfReq6{})) << 16)
	ND6_INFINITE_LIFETIME = 0xffffffff
	IN6_IFF_NODAD         = 0x0020
	IN6_IFF_SECURED       = 0x0400
)

SIOCAIFADDR_IN6 is the same ioctlHandle identifier as unix.SIOCAIFADDR adjusted with size of addrIfReq6.

const SIOCDIFADDR_IN6 = (unix.SIOCDIFADDR & 0xe000ffff) | (uint(unsafe.Sizeof(addrIfReq6{})) << 16)

SIOCDIFADDR_IN6 is the same ioctlHandle identifier as unix.SIOCDIFADDR adjusted with size of addrIfReq6.
