Yes, it's something related to the OS. From the log below:

 COMMAND: ip netns exec h1-n8Aaip ndisc6 -q -r 1 -s 2001:db8:1::1 -w 5000 2001:db8:1::2 eth0.10
 Raw IPv6 socket: Operation not permitted
 TEST: ndisc6                                                        [FAIL]
     rc=1, expected 0

The test is supposed to be run as root so I'm not sure what this error
is about. Do you have something like AppArmor or SELinux running? The
program creates an IPv6 raw socket and requires CAP_NET_RAW.  

Ah, ugh, sorry for the misdirection, you're right.

Confirmed, with the SUID cleared test-bridge-neigh-suppress-sh now
passes on everything with the exception of metal+debug kernel.
