[Bug 1519120] [NEW] Xenial: VLAN interfaces don't work until after a reboot

[Launchpad Bug Tracker]

I tried to use the network manager UI to define a VLAN interface, and
nothing happened. There are a few bugs here:

(1) When creating a VLAN interface through the UI, the "vlan interface
name" must be filled in. This should just default to <interface-
name>.<vid>, rather than being a required field. (I typed in "vlan100"
to get the "Save" button to activate.)

(2) After creating my VLAN interface, nothing happened. No new interface
appeared. I then realized that I had not installed the "vlan" package,
and assumed that NetworkManager therefore could not complete
configuration of the interface.

(3) After installing the 'vlan' package (and then telling NetworkManager
to disconnect and reconnect my Ethernet interface from the UI, just for
good measure), still no VLAN interfaces were present on my system.

I also tried editing the VLAN interface in the UI, and specifying
"enp4s0f1.100", but still no VLAN interface came online.
