Hello, You are very welcome. Also, iSCSI offload cards like the Broadcom (Now owned by Qlogic) are typically called "dependent hardware initiators'. Since it depends on connection to the OS network stack to make it fully functional. Otherwise, it behaves just like a standard NIC.
Cards that completely offload the network and iSCSI functions are known as "Independent hardware initiators'. Since they don't require that OS network connection. They appear solely as a SCSI adapter to the OS. All the network configuration is done on the card. Qlogic used to make the best examples of this. The Qlogic 4xxx series iSCSI HBAs. Now you see this in cards that support DCB, they are called "Converged Network Adapters" CNAs. Since very few Software Initiators support DCB naively the card has to handle everything.
