No problem Avi,
One minor correction to my original reply, I don't the X710/XL710 i40e devices support ipsec offload functionality (at least not from what I can see in their data sheets). The Intel X540 and 82599 family of NICs do have support. Their datasheets have the specifics with regards to capabilities.
Thanks
Ian
