You mean that we do do an exact match for IFA_ADDRESS? Yes that's
exactly what Thomas is trying to fix for IFA_LOCAL.  The only problem
is that people may have come to depend on the "wildcard" match behaviour
of IFA_LOCAL, i.e.:

ip a a dev eth0 192.168.0.1/24
ip a d dev eth0 192.168.0.1

His proposal of encoding a wildcard bit in IFA_LOCAL's prefix length
should solve the problem.

Cheers,
