Some RA implementations (like radvd) dump whatever the user configures
onto the wire, accepting a prefix of "2001:db8:1:0::1/64" without
masking the host bits off.
This causes NetworkManager to send that route down to the kernel, which
*does* mask the host bits off. This causes a mismatch between the
route NetworkManager expects the kernel to create, and what the kernel
actually created, when searching for the kernel object in the platform's
refresh_object() function:
cache = choose_cache (platform, object);
cached_object = nl_cache_search (choose_cache (platform, object), object);
kernel_object = get_kernel_object (priv->nlh, object);
kernel_object is NULL since 'object' (a route which came from the RA
prefix) is not the same as the object the kernel actually did create.
Ensure we match kernel behavior by fixing up prefixes for dumb router
advertisement services.
ndp_open() can fail, do not assume it cannot.
When 'ipv6.disable=1' kernel parameter is used, the whole IPv6 stack is
disabled and the attempt to create PF_INET6 socket fails.

The nm-rdisc subsystem, just as the nm-platform subsystem is separately
testable and it proved convenient to be able to build the test programs
by just typing 'make' in the rdisc/platform directory where the source
code for those modules resides.
src/rdisc doesn't need a makefile just to point to the tests,
we can do that more easily from src/Makefile.am like we do for
all the other tests subdirs.
Abstract class, fake implementation and a manual testing tool for
NetworkManager's internal IPv6 router discovery module. When a real
implementation is ready, it will replace nm-ip6-manager and will be used
by nm-device.
