u8SsidList is a buffer containing a list of hidden SSIDs to
include during the scan. The first byte in the buffer, u8SsidList[0],
is the number of SSIDs encoded in the string. The number of hidden SSIDs
cannot exceed MAX_HIDDEN_SITES. All SSIDs are concatenated in the following
bytes and each SSID is prefixed with a one-byte header containing its length.
The total number of bytes in u8SsidList buffer, including length byte, cannot
exceed 133 bytes (MAX_HIDDEN_SITES SSIDs x 32 bytes each, which is max SSID length).
For instance, encoding the two hidden SSIDs "DEMO_AP" and "TEST"
results in the following buffer content:
@code
uint8 u8SsidList[14];
u8SsidList[0] = 2; // Number of SSIDs is 2
u8SsidList[1] = 7; // Length of the string "DEMO_AP" without NULL termination

@brief
Allow the host MCU app to configure auto TX rate selection algorithm. The application can use this
API to tweak the algorithm performance. Moreover, it allows the application to force a specific WLAN
PHY rate for transmitted data packets to favor range vs. throughput needs.

The Auto rate configuration parameters as listed in tstrConfAutoRate.
@sa
tstrConfAutoRate
@return
The function SHALL return 0 for success and a negative value otherwise.
