Sorry for the late reply. I've been swamped.

Yes, there's no dedicated ILO port.

There was another report on netdev back in 11/2008 on this exact hardware,
with the same problem.

I can't seem to find it. Do you happen to have the subject line or something?

I dug-up my notes on the problem, and from what I can tell, the receive
multicast filters on the NIC were getting removed, causing both incoming
IPv6 and IPv4 multicast packets to get dropped.

Sounds about right. From what I understand the relevant registers were still the same for me when it wasn't working though (if that indeed is how the filter is implemented).
