   4 Subject: [PATCH] wifi: ath11k: Send 11d scan start before WMI_START_SCAN_CMDID
   5
   6 Firmwares advertising the support of triggering 11d algorithm on the
   7 scan results of a regular scan expects driver to send
   8 WMI_11D_SCAN_START_CMDID before sending WMI_START_SCAN_CMDID.
   9 Triggering 11d algorithm on the scan results of a normal scan helps
  10 in completely avoiding a separate 11d scan for determining regdomain.
  11 This indirectly helps in speeding up connections on station
  12 interfaces on the chipsets supporting 11D scan.
  13
  14 To enable this feature, send WMI_11D_SCAN_START_CMDID just before
  15 sending WMI_START_SCAN_CMDID if the firmware advertises
  16 WMI_TLV_SERVICE_SUPPORT_11D_FOR_HOST_SCAN service flag.
  17
  18 WCN6750 & WCN6855 supports this feature.

  21 Tested-on: WCN6855 hw2.1 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23
