   4 Subject: [PATCH] wifi: ath11k: Set ext passive scan flag to adjust passive
   5  scan start time
   6
   7 Set the WMI_SCAN_FLAG_EXT_PASSIVE_SCAN_START_TIME_ENHANCE flag
   8 while sending the scan command.  If this flag is enabled when the
   9 incoming scan request comes with a strict start time and its duration
  10 overlaps with next TBTT, then target adjust the start time accordingly
  11 for passive scan. Target supporting this feature will advertise
  12 WMI_TLV_SERVICE_PASSIVE_SCAN_START_TIME_ENHANCE.
