Drop support for WiMAX for NM 1.2.0+
Review Request #123657 - Created May 6, 2015 and submitted
This patch drops support for WiMAX when using NM 1.2.0+. WiMAX support has been already dropped in NetworkManager and networkmanager-qt. Compiling against nm-qt using NM 1.2.0+ will fail if we do not drop this support in plasma-nm.
