The function is mainly used to enable flow control for advertising reports. When it is enabled,
advertising reports will be discarded by the controller if the number of unprocessed advertising
reports exceeds the size of BLE adv report flow control.
config BT_CTRL_BLE_ADV_REPORT_FLOW_CTRL_NUM
int "BLE adv report flow control number"

range 50 1000
default 100
help
The number of unprocessed advertising report that bluetooth host can save.If you set
`BT_CTRL_BLE_ADV_REPORT_FLOW_CTRL_NUM` to a small value, this may cause adv packets lost.
If you set `BT_CTRL_BLE_ADV_REPORT_FLOW_CTRL_NUM` to a large value, bluetooth host may cache a
lot of adv packets and this may cause system memory run out. For example, if you set
it to 50, the maximum memory consumed by host is 35 * 50 bytes. Please set
`BT_CTRL_BLE_ADV_REPORT_FLOW_CTRL_NUM` according to your system free memory and handle adv
packets as fast as possible, otherwise it will cause adv packets lost.
config BT_CTRL_BLE_ADV_REPORT_DISCARD_THRSHOLD
int "BLE adv lost event threshold value"
depends on BT_CTRL_BLE_ADV_REPORT_FLOW_CTRL_SUPP
range 1 1000
default 20
help
When adv report flow control is enabled, The ADV lost event will be generated when the number
of ADV packets lost in the controller reaches this threshold. It is better to set a larger value.
If you set `BT_CTRL_BLE_ADV_REPORT_DISCARD_THRSHOLD` to a small value or printf every adv lost event, it
may cause adv packets lost more.

## Example Breakdown
- ESP32 does not support the use of main XTAL in light sleep mode, so an external 32kHz crystal is required.
- ESP32C2 does not support the use of 32KHz XTAL in light sleep mode, the XTAL frequency is set to 26MHz in default.
