If you configure esp=aes-md5 it should.
Openswan-3.x.x with OCF support, as far as I know, does not try to hardware
offload IKE, as the speedgains for that were minimal or non-existant, so
having ike= with md5 wouldn't make a difference. I am not sure about
snapgear's OCF patch to openswan 2.4.9 and what it supports or not. David
will probably be able to answer that.
