Resulting in:

ppp[4390]: tun0: IPV6CP: deflink: LayerUp.
ppp[4390]: tun0: ID0: 2 = socket(28, 2, 0)
ppp[4390]: tun0: ID0: -1 = ioctl(2, 2156423451, 0x7fffffffd790)
ppp[4390]: tun0: ID0: bug 218517: errno = 17 (File exists)
ppp[4390]: tun0: Warning: iface add: ioctl(SIOCAIFADDR_IN6,
fe80::a9df:fac8:17ee:204d -> fe80::5aac:78ff:fe22:8f00): Value too large to be

ppp[4390]: tun0: IPV6CP: deflink: LayerDown: fe80::a9df:fac8:17ee:204d

errno must be getting clobbered somewhere between ioctl() and the "iface add"
log line.
