[En-Nut-Discussion] About Multicast packet receive

[Harald Kipp]

Ives,

your observation is correct. In the current status
the Ethernet drivers do not support multicast.

Ethernet controllers have special registers for
multicast mode, which need to be set during
initialization. In case you want to try that,
I'd be very interested in the results.
