[SRU] [B/C] [PATCH 0/1] Allow userspace to change tun's carrier state

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1806392

[Impact]
Userspace cannot change tun's carrier state.

[Fix]
Add .ndo_change_carrier callback for tun.

[Test]
User confirm the backport works.

[Regression Potential]
Low. It add a new function and a new case switch for ioctl, but the new
code doesn't affect existing behavior.
