ndisc: ignore invalid SLAAC prefix lengths (#4923)
- linux does not accept prefixes for SLAAC unequal to 64 bits: http://lxr.free-electrons.com/source/net/ipv6/addrconf.c#L2741 - when networkd tries export such a route to the kernel it will get -EINVAL and set the whole device into a failed state. - this patch will make networkd ignore such prefixes for SLAAC, but process other informations which may contain other prefixes. - Note that rfc4862 does not forbid prefix length != 64 bit
