* wintun: set friendly a bit betterJason A. Donenfeld2019-08-201-22/+10
| | | | | This is still wrong, but NETSETUPPKEY_Driver_FriendlyName seems a bit tricky to use.
* wintun: also set friendly name after setting interface nameJason A. Donenfeld2019-08-191-8/+23

| | | | Performance stays the same as before.
* wintun: merge opening device registry keySimon Rozman2019-08-021-21/+15

* tun: darwin: do not attempt to close tun.event twiceJason A. Donenfeld2019-08-021-4/+1
