The VLAN 0 Priority Tagging Support feature enables 802.1Q Ethernet frames to be transmitted with the VLAN ID tag set to zero.
Example use cases:
BT FTTP circuits
MOCA setups
Supported by Cisco, please do the same:

+1 to this request. Using 802.1p should not be that difficult. VID=0 is a perfectly legal value. Please implement at lease for 98DX32XX switches
This does work already, if you add the port to a single-port bridge as a workaround, and I believe you also have to enable VLAN filtering on the bridge. I agree that there should be an easier way to get this to work without having to jump through those hoops. With a modern Ubuntu system it automatically handles this and you don’t have to do anything special.
It does not work. Yes, you can receive 802.1p-tagged frames with the described workaround, but outbound frames are sent untagged, which breaks connectivity for devices that require 802.1p frame encapsulation to be present.
