Other than one test case (see below), I believe this should be fixed by
the patches I just pushed to the existing branch. My earlier fix was
incomplete which is why it didn't solve the problem.

Should be fixed with the patches.

Nik, the relevant failure is this one:

# TEST: Vlan mcast_startup_query_interval global option default value   [FAIL]
# 	Wrong default mcast_startup_query_interval global vlan option value

Any idea why the kernel will report "mcast_startup_query_interval" as
3124 instead of 3125?

# + jq -e '.[].vlans[] | select(.vlan == 10 and                                             .mcast_startup_query_interval == 3125) '

Please run this one with +x so that we will get more info.

Petr, please take a look. Probably need to make the filters more
specific. The failure is:

# TEST: mirror to gretap: TTL change (skip_hw)                        [FAIL]
# 	Expected to capture 10 packets, got 14.

Should be fixed with the patches.

Not sure about this one. What is the output with the following diff?
