I tried 11.0-CURRENT r274549 with and without patches.
Without patches all works as expected. System encrypts and forwards
traffic with and without aesni module.

With patches software rijndaelEncrypt also works. But when I load
aesni.ko and restart setkey -f /etc/ipsec.conf forwarding stops, errors
counter starts grow. And I see messages about wrong source route
attempts from random addresses.
