// WifiFacade provides simple wrappers to call Wi-Fi HAL APIs.
//
// Each public function returns a tuple: <result, code>, where:
// result: result of HAL API or a mock value (of the correct type)
// on failure.
// code: sl4n_error_codes::kPassInt or sl4n_error_codes::kFailInt on
// success or failure respectively.
//
// The wrapper must check whether or not it is possible to call the API.
// Note the function "SharedValidator()" should be used by wrapper to check
// whether or not the HAL is configured correctly.
