Status in linux package in Ubuntu:

Fix Released
Bug description:
SRU Justification:
------------------
Impact:
WiFi scan stopping issue observed with BLE
Test case:
1) Any PC (Ubuntu Desktop): setup iBeacon advertiser
2) Caracalla 3003 (Ubuntu Server/Core) run:
./scan.sh
By default WiFi supplicant will run on Caracalla
You can check the WiFi scan results by using below command
iw dev wlan0 scan
After 24hrs successful regression, we are unable to get the
WiFi scan results by giving the above command
Fix:
Resolve this by waiting for the confirmation for a management packet from
firmware.
Regression potential:
Below stress tests are conducted to ensure there is no issue in WiFi scan
BLE Scan + WLAN scan
BT Scan + WLAN scan
BLE scan + WLAN connected
Attached are BLE scripts.
