Description Stefano Brivio 2017-07-27 05:33:56 EDT

Found in CI test run at:

    https://beaker.engineering.redhat.com/jobs/1973898

in test:

	Task: (Fail) /kernel/networking/route/route_func - STANDALONE, TEST_TYPE=netns, TEST_TOPO=default, ROUTE_MODE=local
	test: (Fail) Route-Selector-netns-default-local

Add a IPv4 multicast route:
    ip -4 route add multicast 172.111.1.1 dev veth1 table main

and list it:
    ip -4 route list type multicast table main

we get:
    multicast ac6f:101:800:400:400:0:3c00:0 dev veth1 scope link

instead of the expected:
    multicast 172.111.1.1 dev veth1 scope link
