In the NDP tests we search explicitly for a guest address with prefix length 64. AFAICT this is an attempt to specifically find the SLAAC assigned address, rather than something assigned by other means. We can do that more explicitly by checking for .protocol == "kernel_ra". however. The SLAAC prefixes we assigned *will* always be 64-bit, that's hard-coded into our NDP implementation. RFC4862 doesn't really allow anything else since the interface identifiers for an Ethernet-like link are 64-bits. Let's actually verify that, rather than just assuming it, by extracting the prefix length assigned in the guest and checking it as well.
