I think as a prerequisite we need to get all the low-level drivers that implement FMRs to report a max_map_per_fmr value. Unfortunately none of them do right now :(
Indeed, looking at the code of mthca with my limited understanding of it, i could not conclude how hard it would be to implement it there, if you or mellanox can provide some info i might be able to do it.
At the fmr pool level, we can modify the code to use (say) 32 remaps if the max_map_per_fmr attr is 0 and the device max is it is nonzero.
