Subject: IGMP fast leave

Hi,

I'm testing multicast on a router running 2.6.32 kernel.

For fast leave support, I expect that the router should stop sending
immediately the multicast stream when receiving an IGMP leave for the
last member.

2.6.32 kernel does not support this kind of fast leave.
Does latest kernel support it?

Thanks,
Lin Ming
