Add a software bridge and Enable software bridge management

Please follow below steps to add a software bridge and enable software bridge management

1. Implement initialization callback Get the DataFactory instances

Optionally initialization callback can be provided with get manager instance. Data factory will call callback when manager initialization is complete.

auto initCb = [&](telux::common::ServiceStatus status) {
   std::lock_guard<std::mutex> lock(mtx);
   status_ = status;
   initCv.notify_all();
};
 auto &dataFactory = telux::data::DataFactory::getInstance();

2. Get the BridgeManager instances

std::unique_lock<std::mutex> lck(mtx); auto dataBridgeMgr = dataFactory.getBridgeManager(initCb);

3. Wait for BridgeManager initialization to be complete

initCv.wait(lck);

3.1 Check BridgeManager initialization state

BridgeManager needs to be ready to remove a software bridge and disable the software bridge management in the system. If BridgeManager initialization failed, new initialization attempt can be accomplished by calling step 2. If BridgeManager initialization succeed, proceed to step 4

if (status_ == telux::common::ServiceStatus::SERVICE_AVAILABLE) {
   // Go to step 4
}
else {
   //Go to step 2 for another initialization attempt
}

4. Implement callbacks for adding a software bridge and enabling the software bridge management

auto respCbAdd = [](telux::common::ErrorCode error) {
    std::cout << "CALLBACK: "
              << "Add software bridge request"
              << (error == telux::common::ErrorCode::SUCCESS ? " is successful" : " failed")
              << ". ErrorCode: " << static_cast<int>(error)
              << ", description: " << Utils::getErrorCodeAsString(error) << std::endl;
};
auto respCbEnable = [](telux::common::ErrorCode error) {
    std::cout << "CALLBACK: "
              << "Enable software bridge management request is"
              << (error == telux::common::ErrorCode::SUCCESS ? " successful" : " failed")
              << ". ErrorCode: " << static_cast<int>(error)
              << ", description: " << Utils::getErrorCodeAsString(error) << std::endl;
};

5. Add software bridge based on the interface name, interface type and bandwidth required

telux::data::net::BridgeInfo config;
config.ifaceName = infName;
config.ifaceType = infType;
config.bandwidth = bridgeBw;
dataBridgeMgr->addBridge(config, respCbAdd);
