3.4-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 85da53bf1c336bb07ac038fb951403ab0478d2c5 ]
The tests on the flags in addrconf_get_prefix_route() does no make much sense: the 'noflags' parameter contains the set of flags that must not match with the route flags, so the test must be done against 'noflags', and not against 'flags'.
