For sure we would like to offer both, but as mentioned before, this will 
require blk layer instrumentation and ib_core instrumentation to some 
pipeline_mr or something like that.
We are interested in doing this IO path but doing all in 1 series 
doesn't sounds possible.

First we would like to have at least the mutual exclusive solution since 
there are users that may want only one type of acceleration.

re-designing, both blk layer and ib_core for the PI + CRYPTO case in 
this series is not feasible IMO.
