Enable/Disable Firewall

Please follow below steps to Enable/Disable Firewall

1. Get the DataFactory and FirewallManager instances

auto &dataFactory = telux::data::DataFactory::getInstance();
auto dataFwMgr  = dataFactory.getFirewallManager(opType);

2. Check if data subsystem is ready

bool subSystemsStatus = dataFwMgr->isSubsystemReady();

2.1 If data subsystem is not ready, wait for it to be ready

Data subsystems is to make sure that device is ready for services like create and remove DMZ. if subsystems were not ready, wait for unconditionally.

if(!subSystemsStatus) {
   std::future<bool> f = dataFwMgr->onSubsystemReady();
   subSystemsStatus = f.get();
}

3. Implement callback for setting firewall

auto respCb = [](telux::common::ErrorCode error) {
   std::cout << std::endl << std::endl;
   std::cout << "CALLBACK: "
               << "setFirewall Response"
               << (error == telux::common::ErrorCode::SUCCESS ? " is successful" : " failed");
};

4. set firewall mode based on profileId, enable/disable and allow/drop packets

dataFwMgr->setFirewall(profileId,fwEnable, allowPackets, respCb);

5. Response callback will be called for the setFirewall response
