It is initialized at the beginning of the function, and it must contain zero when the "goto exit" is executed.

int mgmt_set_ip(struct beiscsi_hba *phba,
                struct iscsi_iface_param_info *ip_param,
                struct iscsi_iface_param_info *subnet_param,
                uint32_t boot_proto)
{
        struct be_cmd_get_def_gateway_resp gtway_addr_set;
        struct be_cmd_get_if_info_resp *if_info;
        struct be_cmd_set_dhcp_req *dhcpreq;
        struct be_cmd_rel_dhcp_req *reldhcp;
        struct be_dma_mem nonemb_cmd;
        uint8_t *gtway_addr;
        uint32_t ip_type;
        int rc;

        if (mgmt_get_all_if_id(phba))
                return -EIO;

        ip_type = (ip_param->param == ISCSI_NET_PARAM_IPV6_ADDR) ?
                BE2_IPV6 : BE2_IPV4 ;

        rc = mgmt_get_if_info(phba, ip_type, &if_info); <-------------- here
        if (rc)
                return rc;

        if (boot_proto == ISCSI_BOOTPROTO_DHCP) {
                if (if_info->dhcp_state) {
                        beiscsi_log(phba, KERN_WARNING, BEISCSI_LOG_CONFIG,
                                    "BG_%d : DHCP Already Enabled\n");
                        goto exit;
