But the GIFT flag patch works (my understanding is that GIFT flag allows the adapter to transmit stale memory information, it does not have anything to do with cgroups specifically).
Am I missing something? I was only testing the GIFT flag patch.Note: I only turned it on - I did not verify the (non) consitency of the memory that was transmitted.

Are you saying that things worked without actually setting the GIFT flag? In which case why are we adding this flag? - R.
