If DHCP Option 17 is used, the target information is provided by the DHCP server, and the initiator iSCSI
name is retrieved from the value programmed from the Initiator Parameters screen. If no value was
selected, then the controller defaults to the name:
iqn.1995-05.com.broadcom.<11.22.33.44.55.66>.iscsiboot
where the string 11.22.33.44.55.66 corresponds to the controller's MAC address.
If DHCP option 43 (IPv4 only) is used, then any settings on the Initiator Parameters, 1st Target Parameters,
or 2nd Target Parameters screens are ignored and do not need to be cleared.
