Which Host AP version did you use?

Sorry I do not know.

request a scan
int hostap_read_ap_info(struct device *dev)
{
 struct hfa384x_hostscan_request scan_req;
 u16 rate;
 int ret = 0;
 INT oldLevel;
 local_info_t *local = (local_info_t *) dev->priv;

 memset(&scan_req, 0, sizeof(scan_req));
 scan_req.channel_list = __constant_cpu_to_le16(0x000f/*0x3fff*/);
 rate = 2;//HFA384X_RATES_1MBPS;

 scan_req.txrate = cpu_to_le16(rate);
 /* leave SSID empty to accept all SSIDs */
oldLevel = NU_Control_Interrupts(NU_DISABLE_INTERRUPTS);
 if (local->iw_mode == IW_MODE_MASTER) {
  if (hostap_set_word(dev, HFA384X_RID_CNFPORTTYPE,
        HFA384X_PORTTYPE_BSS) ||
      local->func->reset_port(dev))
   printf("Leaving Host AP mode for HostScan failed\n\r");
 }
 if (local->func->set_rid(dev, HFA384X_RID_HOSTSCAN, &scan_req,
     sizeof(scan_req))) {
  printf("HOSTSCAN failed\n\r");
  ret = -EINVAL;
 }
NU_Control_Interrupts(oldLevel);
 NU_Sleep(400);
oldLevel = NU_Control_Interrupts(NU_DISABLE_INTERRUPTS);
 if (local->iw_mode == IW_MODE_MASTER) {
  if (hostap_set_word(dev, HFA384X_RID_CNFPORTTYPE,
        HFA384X_PORTTYPE_HOSTAP) ||
      local->func->reset_port(dev))
   printf("Returning to Host AP mode after HostScan failed\n\r");
 }
NU_Control_Interrupts(oldLevel);

 return ret;
}

read the result
#ifndef PRISM2_NO_DEBUG
 case HFA384X_INFO_HOSTSCANRESULTS:
  prism2_info_hostscanresults(local, buf, left);
  break;
#endif /* PRISM2_NO_DEBUG */
