How about if the MAD layer allocates a response MAD when a MAD is received, and if the process_mad call doesn't actually generate a response the MAD layer just stashed the response MAD away to use for the next receive? This should keep the number of allocations within 1 of the number of responses actually generated, but save us from tracking allocations between two layers.
That sounds reasonable, and I think avoiding allocations in the HCA driver is desirable given the current design.
