Each of these initiator net entries will hold parameters like AF_NET family, IP, subnet (prefix len), gateway (router), vlan ID, etc for the HBA.
Upon a connection request to these persistent targets, the corresponding initiator net entry will get fetched by iscsid and create iface entries out of it for the connection request.
