This is a TAP driver for Solaris, OpenIndiana, SmartOS, and other OpenSolaris derivatives that can be used for:

• OpenVPN
• OpenConnect
• vpnc
• Wireguard
• etc.

The code is based on the Universal TUN/TAP driver. Kazuyoshi Aizawa made changes and added support for Ethernet tunneling, since Universal TUN/TAP driver for Solaris only supports IP tunneling known as TUN.
