I had a question based on some of our customer feedback with this driver.
While running tcrypt mode=10 with Tegra SE driver, it shows errors for lrw(aes),
rfc3686(ctr(aes)) etc. which it does not support.

Algorithms that are not supported by your driver should automatically
be routed to software implementations.  What errors are you getting?
I get the below error. But this is because we don't have CONFIG_LRW
enabled in our defconfig.

[ 1240.771301] alg: skcipher: failed to allocate transform for lrw(aes): -2
[ 1240.778308] alg: self-tests for lrw(aes) using lrw(aes) failed (rc=-2)

So, I suppose enabling the defconfig is the right and only fix here?

Should we be selecting for option for Tegra so there is a clear dependency?
