Jason,

"network connected ipsec accelerator configured using IP packets."
No. This is incorrect.
Where did you get that from?

It is an IPSec-capable NIC.
See here for details:
http://www.mellanox.com/page/products_dyn?product_family=249&mtag=programmable_network_adapters

The driver we are intending to submit for it, interfaces with the mentioned API in the pull-request (Netdev xdo callbacks)

So you configure it from userspace with regular IPSec 'ip xfrm state' commands or over netlink with your favorite IKE daemon.
