It looks like that bridge doesn't see any IPv6 clients:

bridge-stats-end 2016-03-24 17:02:15 (86400 s)
bridge-ips cn=120,us=88,ir=56,ru=48,gb=32,tw=32,[...]
bridge-ip-versions v4=528,v6=0
bridge-ip-transports <OR>=16,obfs3=120,obfs4=400

See the bridge-ip-versions line with v6=0.

Or are you seeing actual IPv6 clients on that bridge that are not
reported there?  In theory, that statistic should be unaffected by
this bug.

Note that even if there are a few dozen IPv6 clients, I'd rather want
to test this patch on a bridge that has at least as many IPv6 clients
as IPv4 clients, because that will tell us whether the patch works or
not.  That's why antirio would be the perfect guinea pig.

All the best,
Karsten
