If for some reason you need to tag traffic outgoing from a vNICs of VMs bridged to a wireless interface in macOS, you can do so as follows.
I will describe this process with VLAN configuration on an OpenWrt router with DSA support.
Open the interfaces tab on the Network menu in LuCI. Switch to the Devices tab and click configure br-lan, then switch to Bridge VLAN filtering and configure as in the screenshot below.
