Hi!

Is there a way to force IGMP version to 2?
I set sysctl variable net.inet.igmp.default_version to 2
but machine still sends IGMP report version 3:

> tcpdump -eni re0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on re0, link-type EN10MB (Ethernet), capture size 65535 bytes

17:39:04.939409 d8:fe:e3:a8:5c:cc > 01:00:5e:00:00:16, ethertype IPv4 (0x0800), length 50: 192.168.210.2 > 224.0.0.22: igmp v3 report, 1 group record(s)

Reboot does not solve a problem.

Thanks in advance!

P.S. 10.2-STABLE, amd64
