I've seen the same problem -- it'll be a generic problem with Ethernet
multicast.
Anyone can set up radvd to test this -- they don't even need proper IPv6
connectivity (although that's trivial to arrange too). They can just set
it up with site-local addresses (the fec0::/16 subnet).
On any machine on the subnet, just 'ip -6 addr add fec0::1/64 dev
eth0' (or whatever the equivalent is in your distribution's network
config scripts), install radvd and set up /etc/radvd.conf to look
something like this...
interface eth1
{
AdvSendAdvert on;
MinRtrAdvInterval 30;
MaxRtrAdvInterval 100;
prefix fec0::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr off;
};
};
You'll find that with the softmac bcm43xx driver, you pick up an address
like fec0::20a:95ff:fef3:9992 automatically, fairly reliably. With the
mac80211 version, it works much more rarely, and slowly. You can tcpdump
and watch for the multicast traffic at both ends.
