Well, I definitely think you've found a card with broken multicast
support.

You should probably contact the author of the driver and see if they
have anything to say about it.  Many drivers don't implement multicast
correctly because the author doesn't use it and therefore can't test it.

What I meant by "hardware problem" is not a problem with your specific
card, but a problem with the chipset itself not doing the right thing.
Multicast support must be present and working in the hardware in order
for it to work in software.  I don't know how common this type of
problem is, and I don't know if there's a way to get around it in
software.
