2b5a8c8f59 selftests: forwarding: Add test cases for unresolved multicast routes 
Add IPv4 and IPv6 test cases for unresolved multicast routes, testing
that queued packets are forwarded after installing a matching (S, G)
route.

The test cases can be used to reproduce the bugs fixed in "ipmr: Always
call ip{,6}_mr_forward() from RCU read-side critical section".

ca059af852 selftests: forwarding: Add reverse path forwarding (RPF) test cases 
In case a packet is routed using a multicast route whose specified
ingress interface does not match the interface from which the packet was
received, the packet is dropped.

Add IPv4 and IPv6 test cases for above mentioned scenario.

6d4efada3b selftests: forwarding: Add multicast routing test 
Introduce basic testing for both IPv4 and IPv6 multicast. The test creates
an (S,G) type route, sends traffic and verifies traffic arrives when the
route is present and then verifies traffic does not arrive after deleting
the route.
This test requires smcroute - https://github.com/troglobit/smcroute which
is a tool that allows creation of static multicast routes.
