Even with IPv6 nd disabled in VMs, there are IPv6 packets coming from
DuT:
--dut_if2_mac ba:dc:0f:fe:02:05
...
dst = 33:33:00:00:00:01
src = ba:dc:0f:fe:02:05
Docker disables IPv6 by default on interfaces it manages, which doesn't
include VF interfaces. Disabling IPv6 in containers using sysctl may fix
this.
