[iPAQ] Bluetooth multicast problem

Hello.

Is there any Bluetooth expert here?

Let ylal be a h3870 with Familiar 0.8.0 and a 2.4.19-rmk6-pxa1-hh37.4
kernel. Let aimlin be a PC with a 2.6.11 kernel and an USB Bluetooth
thingie. There is a bnep link between ylal and aimlin.

If, from ylal, I send an ARP who has broadcast packet on bnep0, aimlin sees
it.

If, from ylal, I send an IPv6 neighbour sollicitation multicast packet,
aimlin does not see the packet (dixunt tcpdump -ni bnep0 and hcidump).

Strangely, neighbour sollicitation works on the other direction.

Is there a way to make it work? I could just "ip neigh add" in the
connection script, but that is not elegant.

By the way, I did not find a package with hcidump for Familiar. Is there
one?

Regards,
