Subject: [Openvpn-devel] [PATCH 5/5] Detect TAP interfaces with root-enumerated 
hardware ID

This patch extends the TAP interface enumerating to detect the TAP
interfaces registered using "root\tap0901" hardware ID. Before, only TAP
interfaces with legacy "tap0901" HWID were detected by openvpn.exe.

The openvpnmsica.dll and tapctl.exe install TAP interfaces using root-
enumerated HWIDs, and were not detected by openvpn.exe.
