I don't think that a standard is actually needed... My naive understanding is that the NIC firmware does packet inspection (no need for deep packet inspection, only MAC and IP headers are enough) and doesn't allow the main system to see that there is a packet if the packet had the BMC as the destination and doesn't allow the BMC to see that there is a packet if the packet had the main system as the destination. Then both the main system and the BMC can use the same way of accessing the NIC, as documented by the NIC vendor - no standard required. Hmmm, actually re-reading what I just wrote, sounds too good to be true so I might miss something :-) -- Bogdan _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
