Hi Eric,
Yes. I will get around to this probably next week.

That is surprising. No I did not compare performance. But I see the 
Qualcomm crypto engine driver enabled and used in the downstream tree 
for this platform. I see no reason for it not to be in mainline and to 
be maintained as an out of tree solution. I will try to run some 
performance benchmarks soon.
