Hi, This patch set clears up the code related to prefix handling when setting IPv6 addresses from DHCPv6. Instead of explicitely tracking prefixes, instruct the kernel not to create routes based on the IPv6 address and its prefix length.
The flag value to use is IFA_F_NOPREFIXROUTE, and as it is longer than the traditional eight bit rtnl flag value, these bigger flag values need to be set with the auxilliary IFA_FLAGS attribute. For completeness, keep on setting the lowermost eight bits in the rtnl flag as before. With this change more code dealing with Router Advertisment prefixes and their disappearance can be removed. I did not do that yet, though, as the code may still be useful in the future - let's see.
