filter QNetworkInterface::hardwareAddress()

[Spitfire]

interfaceFromName() expects interface name returned by QNetworkInterface::name() (ie "{D6637618-7E2B-466B-B02B-C35A1FA9118F}") not QNetworkInterface::humanReadableName().

So, if you want to find interface by human readable name you have to loop through the interfaces and find it yourself.

In the end it's only few lines of code:

QList< QNetworkInterface >  it = QNetworkInterface::allInterfaces();
for( int i = 0; i < it.size(); ++i )
{
    if( it.at( i ).humanReadableName() == "Local Area Connection" )
    {
        qDebug() << it.at( i ).hardwareAddress();
        break;
    }
}

QList< QNetworkInterface >  it = QNetworkInterface::allInterfaces();
for( int i = 0; i < it.size(); ++i )
{
    if( it.at( i ).humanReadableName() == "Local Area Connection" )
    {
        qDebug() << it.at( i ).hardwareAddress();
        break;
    }
}

That works perfectly thanks very much

interfaceFromName() expects interface name returned by QNetworkInterface::name() (ie "{D6637618-7E2B-466B-B02B-C35A1FA9118F}") not QNetworkInterface::humanReadableName().

Is that some Windows perversion? QNetworkInterface::interfaceFromName() works perfectly fine with "eth0", i.e. the same as the humanReadableName(), on Linux.

On linux both are the same but Microsoft invented 'better' way, obviously
