It's not so easy to use openssl with the mv_cesa engine. I used
cryptodev-linux and patches to openssl to test the TDMA stuff, but
perfomance with tinc and openssl was worse than with software crypto.
Probably because of small packetsize and kernel/userspace transfers.
Without cryptodev-linux and patches to openssl, the ioctls on
/dev/crypto fail and openssl falls back to soaftware crypto, which you
can see in your figures.

The main thing the TDMA patch accelerates and for what I use it is
encryted block devices with dm-crypt.
