* This function returns concatenated payload of possibly fragmented vendor
* specific information elements in the scan result. The caller is responsible

* This function is like wpa_scan_get_vendor_ie_multi(), but uses IE buffer only
* from Beacon frames instead of either Beacon or Probe Response frames.
