I often come accross network cards with iSCSI offload engines such as the Broadcom BCM5709 (eg. I have them in Dell servers with linux and open-iscsi initiators), but there are other similar cards on the market.
When using such a card in a FreeNAS system acting as iSCSI target, does the offload engines "kick in" and actually offload work from the main CPU, or is that an initiator-only feature?
