hwcrypto offloads cryptography to the device. It saves host CPU cycles
so it's a good thing to do. The bug #519154 doesn't affect most people
and only for 4965. #556990 doesn't look like swcrypto related, need to
do more investigation. So I don't think we should use swcrypto=1 by
default in upstream. Users are free to do so in their /etc/modprobe.d
though.
