[Interest] QNetworkInterface working differently on Qt5?

[Tom Isaacson]

Did a bit more debugging and it seems that QNetworkInterface:: allAddresses() does return all the IP addresses but QNetworkInterface::addressEntries() only returns 1.

>Our app uses QNetworkInterface::allInterfaces() then steps through it calling QNetworkInterface::addressEntries() to get the IP addresses. This works fine on >Qt 4.8.2 but since we moved to Qt 5.5.1 we're only getting the zeroconfig address from eth0. Has QNetworkInterface changed in Qt5 or is this a known bug?
