Hi!

We're seeing a few more flakes on vxlan-bridge-1q-mc-ul-sh and
vxlan-bridge-1q-mc-ul-sh in the new setup than we used to (tho
the former was always relatively flaky).

# 141.78 [+13.13] TEST: VXLAN MC flood IPv6 mcroute changelink                        [FAIL]
# 141.78 [+0.00] Expected 10 packets on H2, got 11
# 141.83 [+0.04] smcroutectl: mroute: deleting route from lo10 (192.0.2.33/32,233.252.0.1/32)

Perhaps we should make the filter more specific to the test traffic?

LMK if you need access to the system.
