max devices in tun

[Akilan Elango]

Hey guys,
    I was fiddling around with the /dev/tun to write a TUN interface
for my app. I wanted to check what is the max amount of interfaces
that can be made. Turned out it was 32768 [0 - 32768). But when I
created (ifconfig tun32768 create), a weird device appeared as shown
in this figure : https://imgur.com/a/0ypbwgg.

Is this expected? and I'm unable to delete the device too from ifconfig.
